Source: https://sec-api.io/docs/form-13-f-filings-institutional-holdings-api

The Form 13F API provides the **portfolio holdings** and **cover pages** that institutional investment managers report to the SEC on Form 13F. The data covers holdings from the first quarter of 2013 to the present, and older 13F filings back to 1998 with their filing details, but without holdings. Each holding includes the issuer, security class, CUSIP, ticker, CIK, market value, number of shares or principal amount, put or call, investment discretion and voting authority. The cover pages contain the name, CIK and CRD number of the manager, the report period, the number of holdings, the total portfolio value and the other managers included in the report. All fields are searchable. For example, a search can list all managers that held a given stock in a given quarter.

**Portfolio Holdings**
The API provides information on current and historical portfolio holdings of SEC-registered funds and investment managers, including issuer name, title of the securities class, CUSIP, CIK and ticker of the holding, value of the position in dollar, the number of shares held, and more.

**Cover Page Information**
The cover pages of 13F filings include defails about the fund or manager, such as their name, CRD and CIK, gross market value of the porfolio and details about other included managers.

Portfolio holdings from the Form 13F database can be retrieved and searched using various parameters, including name, CIK and CRD of the fund or manager, filing publication date and quarter-year period the filing references (e.g., Q3 2024). All CUSIPs are pre-mapped to their respective ticker symbols and CIKs, enabling searches for 13F filings that disclose positions in specific companies using ticker symbols. The API provides access to the complete historical holdings data for every fund and investment manager registered with the SEC. This data is accessible via a REST API, compatible with Python, C#, Node.js, R, and any other programming language.

An example search query to list all funds and managers invested in Tesla is available [in the API playground here](https://sec-api.io/sandbox/13f-filings-holding-tesla). This example retrieves the most recent 13F-HR filings and portfolio holdings that include Tesla's CUSIP `88160R101`, showing which funds bought or sold Tesla securities over time.

[Our Python tutorial](https://medium.com/@jan_5421/analyzing-13f-sec-filings-and-buy-sell-activities-of-institutional-investment-managers-using-python-8bba3dfafd7d) demonstrates how to extract and analyze the buy and sell activities of institutional investment managers from 13F filings and visualize changes in fund holdings over time.

Database size:

All 13,000+ funds and investment managers registered with the SEC since 1994 to present and over 300,000 SEC Form 13-F filings are available.

Database history:

The 13F database includes metadata for all 13F-HR filings from 1998 to present, as well as 13F-E filings from 1994 to 1998. It provides holdings information and cover pages in structured JSON format for all SEC-registered funds and investment managers starting from 2013.

Data update frequency:

Newly disclosed portfolio holdings and cover page information are extracted, indexed, and made searchable within an average of 300 milliseconds after a new 13F filing is published.

Survivorship bias free:

Yes. The 13F database includes portfolio holdings and cover pages from funds and managers that ceased filing 13F reports.

## Use Cases

The Form 13F API and database is used for various purposes in investment research, portfolio management, and financial analysis. Common use cases for real-time monitoring and historical analysis of investment managers' portfolios include:

- Rebalancing of replicated index portfolios that mirror the holdings of top-performing managers.
- Backtesting investment strategies by analyzing historical changes in fund holdings.
- Crowding analysis to identify popular stocks among institutional investors to reduce the risk of overexposure.
- Identifying new investment opportunities by analyzing cross-sectional buy and sell activities of investment managers.
- Monitoring post-IPO institutional investment activities by tracking the number of shares bought or sold by investment managers.

## API Endpoints

### Institutional Holdings in Form 13F Filings

The Institutional Holdings API returns all holdings data of each Form 13F filing. To find and retrieve 13F holdings data, send an HTTP `POST` request with the desired search parameters to the following endpoint:

https://api.sec-api.io/form-13f/holdings

Supported HTTP methods: `POST`

Request and response content type: `JSON`

### Cover Pages in Form 13F Filings

The Cover Pages API provides access to all cover pages of Form 13F filings. To retrieve 13F cover pages, send an HTTP `POST` request with the desired search parameters to the following endpoint:

https://api.sec-api.io/form-13f/cover-pages

Supported HTTP methods: `POST`

Request and response content type: `JSON`

### Bulk Download Endpoints

The bulk download endpoints allow retrieving dataset files of Form 13F holdings and cover pages in a structured format. Each file is provided in JSONL (JSON Lines) format, where each line is a standalone JSON object - ideal for large-scale data processing.

There are two types of datasets available for bulk download:

- **Holdings Data:** Contains portfolio holdings from all 13F filings within a specific year-month period, based on the filing's `filedAt` date.
- **Cover Pages:** Includes cover pages of all 13F filings for a given year and month, based on the filing's `filedAt` date.

In addition, `index.json` files list all available JSONL files along with their paths, last update timestamps, and file sizes - helpful for programmatic access and identifying when a specific file was last updated. All `.jsonl.gz` and `index.json` files are updated once daily between 1:00 AM and 5:00 AM (ET), reflecting all 13F filings published the previous day.

#### Examples

- `https://api.sec-api.io/bulk/form-13f/holdings/2024/2024-01.jsonl.gz`
- `https://api.sec-api.io/bulk/form-13f/holdings/index.json`

### Authentication

To authenticate API requests, use the API key shown in your [user profile](https://sec-api.io/login). Utilize the API key in one of two ways. Choose the method that best fits your implementation:

- **Authorization Header:** Include the API key as an `Authorization` header. For instance, before sending a `POST` request to `https://api.sec-api.io/form-13f/holdings`, ensure the header is set as follows: `Authorization: YOUR_API_KEY`
- **Query Parameter:** Alternatively, append the API key directly to the URL as a query parameter. For example, when making `POST` requests, use the URL `https://api.sec-api.io/form-13f/holdings?token=YOUR_API_KEY` instead of the base API endpoint.

## Request Parameters

The Holdings and Cover Pages API both accept a JSON payload including the search parameters to specify what holdings or cover pages to retrieve. The structure of the JSON payload is the same for both APIs.

```json
{
  "query": "cik:1633901 AND periodOfReport:[2023-01-01 TO 2023-12-31]",
  "from": "0",
  "size": "10",
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

The request payload includes the following fields:

- `query` (string): Specifies the search string written in the Lucene syntax like `field:value` to look for all holdings or cover pages that include `value` in the `field`. For example, use `periodOfReport:[2023-01-1 TO 2023-06-30]` to find all holdings reported in 13F-HR filings for the first half of 2023. A complete guide on [how to use the Lucene syntax is available here](https://sec-api.io/resources/lucene-query-syntax-overview).
- `from` (string, optional) - Use the `from` property to specify the starting position of the search results, facilitating pagination. For instance, set `from` to 50 to skip the first 50 results. The default is 0, and the maximum allowed value is 10,000, which is also the cap for the maximum number of filings or cover pages returned per `query` string. To retrieve and paginate through all matches in the search universe, increment `from` by the value of the `size` parameter (e.g., 50) until no more results are returned or the 10,000 limit is reached. For example, use `0`, `50`, `100`, and so on. If the `query` locates more than 10,000 matches, consider narrowing the search universe by refining the filter criteria, for example, using a date range filter to iterate over months or years. One such approach would be to search for filings with a `filedAt` date range filter, e.g. `filedAt:[2021-01-01 TO 2021-01-31]` (all filings from January 2021), then paginate through the results by incrementing `from`, and once completed, repeat the process for the next month, and so on.
- `size` (string, optional) - Determines the number of filings or cover pages returned per request. For instance, set `size` to 10 to retrieve 10 filings per request. The default value is 50, and the maximum allowed value is 50, which is the cap for the maximum number of filings or cover pages returned per request.
- `sort` (array, optional) - An array of objects that specify how the returned results are sorted. The default sorting order is descending by `filedAt` datetime field, most recent filing first. The sorting order can be changed to ascending by setting `order` to `asc`. The default sorting order can be overridden by specifying a different sorting field. For example, to sort results by `periodOfReport` in ascending order, set `sort` to `[{ "periodOfReport": { "order": "asc" } }]`.
  Default: `[{ "filedAt": { "order": "desc" } }]`

### Request Examples

#### Form 13F Filings, Cover Pages and Holdings by CIK

Using the CIK search expression, retrieve the 10 most recent Form 13F filings with their associated holding information for Ritholtz Wealth Management with CIK 1633901 (`POST /form-13f/holdings`) or the cover pages (`POST /form-13f/cover-pages`) for the same CIK.

}
```

#### Form 13F Filings of Registered Investment Adviser (RIA) by CRD Search

Finding all Form 13F filings of a Registered Investment Adviser (RIA) using its CRD number is a simple two-step process: locate the accession number of the latest 13F filing via a CRD number search with the Cover Pages API, then use the accession number to retrieve the filing metadata and holdings data via the Holdings API.

Demonstrated below is the process to locate the latest 13F filing of Bridgewater Associates with CRD number 105129. First, find the accession number of the latest 13F filing by searching the Cover Pages API with the CRD number in the `query` parameter, for example `crdNumber:105129` for Bridgewater Associates, and sort the results by `periodOfReport` in descending order to get the most recent filing first.

```json
{
  "query": "crdNumber:105129",
  "from": "0",
  "size": "20",
  "sort": [{"periodOfReport":{"order":"desc"}}]
}
```

The response will include the accession number of the latest 13F filing, for example:

JSON - Response Example for CRD Search

```json
{
  "total": { "value": 12, "relation": "eq" },
  "data": [
    {
      "accessionNo": "0001172661-25-004777",
      "filedAt": "2025-11-13T16:36:48-05:00",
      "cik": "1350694",
      // ... more cover page attributes
    }
    // ... more cover page objects
  ]
}
```

Use the retrieved accession number to access the filing metadata and holdings data via the Holdings API by searching with the accession number in the `query` parameter, for example: `accessionNo:"0001172661-25-004777"`.

```json
{
  "query": "accessionNo:\"0001172661-25-004777\"",
  "from": "0",
  "size": "1"
}
```

JSON - Response Example for Search by Accession Number

          "type": "INFORMATION TABLE",
          // ...
        }
      ],
      // ... more filing attributes + holdings
    }
  ]
}
```

The URL to the filing's overview page is located in the `linkToHtml` attribute of the response object. The cover page URL is located in the `linkToFilingDetails` attribute, while the URL of the holdings table is found in the third object of the `documentFormatFiles` array under `documentUrl`.

Refer to the following sections for detailed information on the response format of each endpoint.

- [Response format of /holdings endpoint](#holdings-response-format)
- [Response format of /cover-pages endpoint](#cover-pages-response-format)

### Form 13F - Holdings

The Holdings API returns the holdings data of each Form 13F filing in JSON format. The API response includes two fields: `total` (object) and `data` (array of objects). The `total` object provides metadata about the search results, such as the total number of filings matching the search criteria. The `data` array contains 13F filings and their holdings data. Each 13F filing includes an array of holding objects, where each array item represents information about one holding in the fund's portfolio. The attributes of each holding include:

- `nameOfIssuer` (string) - Column 1: Name of the issuer of the security either abbreviated or as it appears in the [Official List of Section 13F Securities published by the SEC](https://www.sec.gov/divisions/investment/13flists), e.g. MICRON TECHNOLOGY INC
- `titleOfClass` (string) - Column 2: Title of class, e.g. COM
- `cusip` (string) - Column 3: Nine-digit CUSIP number of security, e.g. 98850P109
- `ticker` (string) - Ticker of security, e.g. TSLA
- `cik` (string) - CIK of security, e.g. 1004434. Leading zeros are removed.
- `value` (integer) - Column 4: The absolute market value of the position denoted in dollars, e.g. 120,000,000. The value typically represents the value at the close of trading on the last trading day of the quarter. For older filings, the API automatically multiplies the value by 1000, e.g. 120,000 becomes 120,000,000.
- `shrsOrPrnAmt` (object) - Column 5: Amount and type of security.
  - `sshPrnamt` (integer) - Total number of shares of the class of security or the principal amount of such class, e.g. 345,000
  - `sshPrnamtType` (string) - Security type of the position. `SH` denotes shares, `PRN` denotes principal amount.
- `putCall` (string, optional) - If the holding represents an option, the type of option. Possible values: `Call`, `Put`.
- `investmentDiscretion` (string) - Column 6: Holdings are segregated according to the nature of the investment discretion held by the manager. Investment discretion can be `SOLE` (sole investment discretion), `DEFINED` (shared-defined investment discretion), or `OTHER` (shared-other investment discretion).
- `otherManager` (string, optional) - Column 7: Other manager. The number assigned to the other manager sharing investment discretion over the holding as defined in the "List of Other Included Managers" section on the cover page of the Form 13F filing. For example, `1`.
- `votingAuthority` (object) - Column 8: Voting authority. The number of shares for which the manager exercises sole, shared, or no voting authority (none).
  - `Sole` (integer) - Sole, e.g. 345
  - `Shared` (integer) - Shared, e.g. 345
  - `None` (integer) - None, e.g. 345

#### Investment Discretions

Sole:

An investment manager with sole investment discretion has the exclusive authority to make investment decisions regarding the security without requiring the consent or approval of any other party. This authority means that the manager is fully responsible for deciding whether to buy, sell, or hold a security and is not obligated to seek input from or share decision-making power with another entity or person.

Shared:

Multiple investment managers share the authority to make investment decisions regarding the security. This means that two or more managers have collective discretion over whether to buy, sell, or hold that security, either because of a collaborative agreement, the nature of the investment management structure, or an explicit understanding about how decisions should be made.

#### Types of Report

The `reportType` attribute indicates the type of 13F report filed by the investment manager. The following three types are available:

13F Holdings Report:

If the manager reports all securities under their investment discretion in this filing, the value will be `13F HOLDINGS REPORT`. In this case, the cover page will omit the `otherManagersReportingForThisManager` value and both the summary on the cover page and holdings information table will be included in the filing.

13F Notice:

If all securities under the manager's investment discretion are reported by another manager, the value will be `13F NOTICE`. In this case, the cover page will include the `otherManagersReportingForThisManager` property, while both the summary on the cover page and holdings information table will be omitted in the filing.

13F Combination Report:

If only a portion of the securities under the manager's investment discretion is reported by another manager, the value will be `13F COMBINATION REPORT`. In this case, the cover page will include the `otherManagersReportingForThisManager` property, along with both the summary on the cover page and the holdings information table.

## FAQ

Common questions about querying the Form 13F Institutional Holdings API, the response shape, and the bulk archives.

### How do I look up the most recent portfolio holdings reported by a specific investment manager?

Use the `/form-13f/holdings` endpoint and filter on the investment manager's SEC identifier so that the filing manager CIK (`cik`) equals the manager you are researching, for example `1633901` for Ritholtz Wealth Management. To get the latest portfolio first, sort the results in descending order by the filing publication timestamp (`filedAt`) so the most recently published 13F-HR filing is returned at the top.

Each matching filing carries the full portfolio in the `holdings` array, where every entry describes one position with its issuer name (`holdings.nameOfIssuer`), ticker (`holdings.ticker`), dollar market value (`holdings.value`), and share count (`holdings.shrsOrPrnAmt.sshPrnamt`). Taking the first result gives you the manager's current disclosed portfolio.

```json
{
  "query": "cik:1633901",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How can I retrieve a fund's portfolio for a particular quarter, for example the third quarter of 2024?

Use the `/form-13f/holdings` endpoint and filter on the reporting period field (`periodOfReport`), which holds the last calendar day of the quarter the filing covers. For the third quarter of 2024 the value of `periodOfReport` should be `2024-09-30`; the first quarter ends `03-31`, the second `06-30`, and the fourth `12-31`. Combine this with the filing manager CIK (`cik`) of the specific fund you are studying to isolate that fund's report for the quarter.

The returned filing contains the disclosed positions in its `holdings` array. Note that 13F filings are usually published several weeks after the quarter closes, so the `filedAt` timestamp will be later than the `periodOfReport` date.

```json
{
  "query": "cik:1633901 AND periodOfReport:2024-09-30",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I pull all four quarterly portfolio reports a manager filed during a single year?

Use the `/form-13f/holdings` endpoint and filter on both the manager's identifier and the reporting period. The filing manager CIK (`cik`) should equal the manager you are researching, and the reporting period (`periodOfReport`) should fall within a one-year window, for example between `2020-01-01` and `2020-12-31`. This matches the four quarterly 13F-HR filings whose period-end dates are `2020-03-31`, `2020-06-30`, `2020-09-30`, and `2020-12-31`.

Sorting the results by `periodOfReport` in ascending order returns the quarters in chronological order, and each filing's `holdings` array holds that quarter's disclosed positions.

```json
{
  "query": "cik:1737109 AND periodOfReport:[2020-01-01 TO 2020-12-31]",
  "from": 0,
  "size": 50,
  "sort": [{"periodOfReport":{"order":"asc"}}]
}
```

### How do I find which institutional investors hold a particular stock by its ticker symbol?

Use the `/form-13f/holdings` endpoint and filter on the ticker of the holding (`holdings.ticker`), for example `TSLA` for Tesla. Because every CUSIP in the dataset is pre-mapped to its ticker, this matches any 13F-HR filing whose portfolio contains at least one position in that company, including common stock, warrants, options, or notes.

Each matching filing identifies the institutional investor by the filing manager name (`filingManager.name`) and CIK (`cik`), and the relevant position appears inside the `holdings` array with its value (`holdings.value`) and share count (`holdings.shrsOrPrnAmt.sshPrnamt`). Sorting by `filedAt` in descending order surfaces the most recent disclosures first.

```json
{
  "query": "holdings.ticker:TSLA",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How can I find every fund holding a company when I only know its CUSIP and not its ticker?

Use the `/form-13f/holdings` endpoint and filter on the nine-digit CUSIP of the holding (`holdings.cusip`), for example `88160R101` for Tesla common stock. The CUSIP appears on every position in the `holdings` array, so this matches any filing whose portfolio discloses that security even when no ticker is available.

Each matching filing identifies the holder by the filing manager name (`filingManager.name`) and CIK (`cik`). Note that a single company can have several CUSIPs for different share classes or security types, so each CUSIP isolates one specific class.

```json
{
  "query": "holdings.cusip:88160R101",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I find institutional investors holding a company identified by its SEC company identifier rather than its ticker?

Use the `/form-13f/holdings` endpoint and filter on the CIK of the security itself (`holdings.cik`), which is the SEC Central Index Key of the company being held, for example `1318605` for Tesla. This is distinct from the top-level `cik` field, which identifies the filing manager rather than the issuer.

Matching filings each contain the position in their `holdings` array alongside the issuer name (`holdings.nameOfIssuer`), and the holding institution is identified by the filing manager name (`filingManager.name`) and the top-level `cik`.

```json
{
  "query": "holdings.cik:1318605",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I retrieve a single 13F filing and its holdings when I already have its accession number?

Use the `/form-13f/holdings` endpoint and filter on the accession number (`accessionNo`), which uniquely identifies one 13F filing, for example `0001172661-25-004777`. Searching by this exact value returns that single filing together with its complete `holdings` array.

The response also carries links to the source documents on EDGAR: the filing overview page in `linkToHtml`, the cover page document in `linkToFilingDetails`, and the information table URL inside the `documentFormatFiles` array under `documentUrl`.

```json
{
  "query": "accessionNo:\"0001172661-25-004777\"",
  "from": 0,
  "size": 50
}
```

### How can I find all 13F filings submitted within a specific date range?

Use the `/form-13f/holdings` endpoint and filter on the filing publication timestamp (`filedAt`), which records when the 13F filing was submitted to the SEC. Set the range so that `filedAt` falls between your start and end dates, for example between `2020-01-01` and `2020-01-31` to capture all filings published in January 2020.

This is distinct from the reporting period (`periodOfReport`), which reflects the quarter the filing covers rather than when it was filed. Sorting by `filedAt` in descending order returns the most recent filings first within the window.

```json
{
  "query": "filedAt:[2020-01-01 TO 2020-01-31]",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I look up an investment adviser's filings using its CRD registration number instead of its CIK?

Use the `/form-13f/cover-pages` endpoint and filter on the CRD number of the filing manager (`crdNumber`), the registration number assigned to a Registered Investment Adviser, for example `105129` for Bridgewater Associates. Sorting the cover pages by `periodOfReport` in descending order puts the most recent filing first.

Each cover page returns the accession number (`accessionNo`) of the corresponding filing. To then retrieve the full portfolio, take that accession number and query the `/form-13f/holdings` endpoint by `accessionNo`, which returns the filing metadata and its `holdings` array.

```json
{
  "query": "crdNumber:105129",
  "from": 0,
  "size": 50,
  "sort": [{"periodOfReport":{"order":"desc"}}]
}
```

### How do I get the headline portfolio summary for a fund, such as its total reported portfolio value and number of positions, without pulling every holding?

Use the `/form-13f/cover-pages` endpoint, which returns the cover page of each 13F filing without the full position list. Filter on the filing manager CIK (`cik`) of the fund you are researching and sort by `filedAt` in descending order for the latest filing.

The cover page reports the headline figures directly: the total dollar value of the portfolio is in `tableValueTotal`, and the number of disclosed positions is in `tableEntryTotal`. The fields `tableValueTotalAsReported` and `tableEntryTotalAsReported` hold the same figures as originally stated by the manager. These values let you read a fund's portfolio size without retrieving every holding.

```json
{
  "query": "cik:1633901",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How can I identify which funds disclose options positions such as puts and calls?

Use the `/form-13f/holdings` endpoint and filter on the option-type field of the holdings (`holdings.putCall`), requiring it to be present with any value. This field is only populated when a position represents an option, so matching filings are those that disclose at least one put or call.

Each matching filing is identified by the filing manager name (`filingManager.name`) and CIK (`cik`), and the specific option positions appear in the `holdings` array where `holdings.putCall` is set to either `Put` or `Call`.

```json
{
  "query": "holdings.putCall:*",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I separate a fund's put option exposure from its call option exposure in its disclosed positions?

Use the `/form-13f/holdings` endpoint and read the option-type field on each holding (`holdings.putCall`). A value of `Put` marks a put option position and a value of `Call` marks a call option position; positions in equities and other non-option securities leave this field empty.

To isolate one side of a fund's options book, filter on the filing manager CIK (`cik`) of the fund and on `holdings.putCall` being `Put` for put exposure, or `Call` for call exposure. Within each matching filing, the relevant positions in the `holdings` array carry their dollar value (`holdings.value`) and contract amount (`holdings.shrsOrPrnAmt.sshPrnamt`).

```json
{
  "query": "holdings.putCall:Put",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I find filings where a manager exercises no voting authority over a large share of its holdings?

Use the `/form-13f/holdings` endpoint and read the voting authority breakdown on each holding (`holdings.votingAuthority`), which splits the share count into `holdings.votingAuthority.Sole`, `holdings.votingAuthority.Shared`, and `holdings.votingAuthority.None`. A position where `holdings.votingAuthority.None` carries the bulk of the shares while `Sole` and `Shared` are zero indicates the manager holds no voting power over it.

After retrieving a manager's filings by filtering on the filing manager CIK (`cik`), compare these three counts across the entries in the `holdings` array to gauge how much of the portfolio is held without voting authority.

```json
{
  "query": "cik:1633901",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I tell whether a holding is reported as a share count or as a principal amount of debt?

Use the `/form-13f/holdings` endpoint and read the amount-type field inside each holding's quantity object (`holdings.shrsOrPrnAmt.sshPrnamtType`). A value of `SH` means the quantity in `holdings.shrsOrPrnAmt.sshPrnamt` is a number of shares, while a value of `PRN` means it is the principal amount of a debt security.

The numeric quantity itself is always in `holdings.shrsOrPrnAmt.sshPrnamt`, so reading the type alongside it tells you whether a position is equity-style or debt-style. Filtering on `holdings.shrsOrPrnAmt.sshPrnamtType` being `PRN` isolates filings that disclose debt holdings.

```json
{
  "query": "holdings.shrsOrPrnAmt.sshPrnamtType:PRN",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I find only the corrected or restated versions of institutional holdings filings?

Use the `/form-13f/holdings` endpoint and filter on the form type field (`formType`) so that it equals `13F-HR/A`, the form type used for amendments to a 13F holdings report. Alternatively, filter on the amendment flag (`isAmendment`) being `true`, which is set on every corrected or restated filing.

To narrow further to a particular quarter, add a condition on the reporting period (`periodOfReport`), for example `2020-12-31` for fourth-quarter 2020 amendments. Each amended filing carries its corrected portfolio in the `holdings` array.

```json
{
  "query": "formType:\"13F-HR/A\" AND periodOfReport:2020-12-31",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How can I distinguish an amendment that restates a whole portfolio from one that merely adds new positions?

Use the `/form-13f/cover-pages` endpoint and read the amendment detail object (`amendmentInfo`), which is populated only on amended filings. The amendment type field (`amendmentInfo.amendmentType`) holds `RESTATEMENT` when the amendment replaces the entire portfolio, and `NEW HOLDINGS` when the amendment only adds further holdings entries to a previously filed report.

The object also carries the amendment sequence in `amendmentInfo.amendmentNo`. Filter on `amendmentInfo.amendmentType` being `RESTATEMENT` or `NEW HOLDINGS` to isolate one kind of correction.

```json
{
  "query": "amendmentInfo.amendmentType:RESTATEMENT",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I identify filings where a manager reports no holdings of its own because another manager reports on its behalf?

Use the `/form-13f/cover-pages` endpoint and filter on the report type field (`reportType`) so that it equals `13F NOTICE`. A notice filing is submitted when all securities under a manager's investment discretion are reported by another manager, so the filing itself omits both the portfolio summary and the holdings table.

On these filings the array of managers reporting on this manager's behalf (`otherManagersReportingForThisManager`) is populated, with each entry giving the other manager's name (`otherManagersReportingForThisManager.name`) and CIK (`otherManagersReportingForThisManager.cik`).

```json
{
  "query": "reportType:\"13F NOTICE\"",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How can I find filings that combine a manager's own holdings with positions reported by other managers?

Use the `/form-13f/cover-pages` endpoint and filter on the report type field (`reportType`) so that it equals `13F COMBINATION REPORT`. A combination report is filed when only a portion of the securities under a manager's discretion is reported by another manager, so the filing includes both the cover page summary and a holdings table for the remainder.

On these filings the array of managers reporting on this manager's behalf (`otherManagersReportingForThisManager`) is populated with each other manager's name and CIK, and the manager's own positions can be retrieved from the `holdings` array of the corresponding filing on the `/form-13f/holdings` endpoint.

```json
{
  "query": "reportType:\"13F COMBINATION REPORT\"",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I find the related sub-advisors or affiliated managers grouped under a single 13F filing?

Use the `/form-13f/cover-pages` endpoint and read the array of other included managers (`otherIncludedManagers`), which lists the affiliated managers or sub-advisors whose positions are aggregated into the filing. Each entry gives that manager's sequence number (`otherIncludedManagers.sequenceNumber`), name (`otherIncludedManagers.name`), CIK (`otherIncludedManagers.cik`), and CRD number (`otherIncludedManagers.crdNumber`).

The count of these managers is also available directly in `otherIncludedManagersCount`. Filtering for filings where `otherIncludedManagersCount` is greater than zero isolates filings that group multiple affiliated managers together.

```json
{
  "query": "otherIncludedManagersCount:[1 TO *]",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I find filings from investment managers located in a particular state?

Use the `/form-13f/cover-pages` endpoint and filter on the state or country field within the filing manager's address (`filingManager.address.stateOrCountry`), for example `NY` for New York or `CA` for California. This field holds the two-letter state code, or a country code for managers based outside the United States.

The full address is also available through `filingManager.address.street`, `filingManager.address.city`, and `filingManager.address.zipCode`, and each matching cover page identifies the manager by name in `filingManager.name`.

```json
{
  "query": "filingManager.address.stateOrCountry:NY",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How can I search for a fund by its management company name rather than by an identifier?

Use the `/form-13f/cover-pages` endpoint and filter on the filing manager name field (`filingManager.name`), which holds the management company's name as stated on the filing, for example `Corsair Capital LLC` or `Navellier & Associates Inc`. This lets you locate a fund without first knowing its CIK or CRD number.

Each matching cover page returns the manager's identifiers, including the filing manager CIK (`cik`) and CRD number (`crdNumber`), which you can then use for precise follow-up queries on the `/form-13f/holdings` endpoint.

```json
{
  "query": "filingManager.name:\"Navellier & Associates Inc\"",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I get the contact details and the name and title of the person who signed a fund's filing?

Use the `/form-13f/cover-pages` endpoint and read the signature object (`signature`), which records who signed the 13F filing on behalf of the manager. The signer's name is in `signature.name`, their role in `signature.title`, and a contact phone number in `signature.phone`.

The same object also carries the signature text (`signature.signature`), the signer's city (`signature.city`) and state or country (`signature.stateOrCountry`), and the date the filing was signed (`signature.signatureDate`).

```json
{
  "query": "cik:1633901",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I track how a fund's position in one stock changed across consecutive quarters?

Use the `/form-13f/holdings` endpoint and filter on both the filing manager CIK (`cik`) of the fund and the ticker of the holding (`holdings.ticker`) for the stock you are tracking, for example `AMD`. Sorting by `periodOfReport` in ascending order returns the fund's filings in chronological quarterly order.

For each quarter, locate the matching entry in the `holdings` array and compare its share count (`holdings.shrsOrPrnAmt.sshPrnamt`) and dollar value (`holdings.value`) against the prior quarter. A rising share count indicates accumulation, a falling count indicates trimming, and the disappearance of the position indicates a full exit.

```json
{
  "query": "cik:1633901 AND holdings.ticker:AMD",
  "from": 0,
  "size": 50,
  "sort": [{"periodOfReport":{"order":"asc"}}]
}
```

### How can I measure how crowded a stock is among institutional investors by counting how many funds hold it in a given quarter?

Use the `/form-13f/holdings` endpoint and filter on the ticker of the holding (`holdings.ticker`) for the stock you are studying, together with the reporting period (`periodOfReport`) set to the quarter-end date, for example `2024-09-30` for the third quarter of 2024.

The response carries a `total` object whose `total.value` field reports the total number of filings matching the query. Because each 13F-HR filing represents one institutional manager, that count is the number of funds holding the stock in that quarter, which serves as a measure of how crowded the position is.

```json
{
  "query": "holdings.ticker:TSLA AND periodOfReport:2024-09-30",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How do I rank a fund's largest positions by dollar value for its latest portfolio report?

Use the `/form-13f/holdings` endpoint and filter on the filing manager CIK (`cik`) of the fund, sorting by `filedAt` in descending order to retrieve its latest 13F filing first. That filing's portfolio is in the `holdings` array.

Each holding records its absolute market value in dollars (`holdings.value`). Ordering the entries in the `holdings` array by `holdings.value` in descending order produces the fund's largest positions, with the issuer named in `holdings.nameOfIssuer` and the size in `holdings.shrsOrPrnAmt.sshPrnamt`.

```json
{
  "query": "cik:1633901",
  "from": 0,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}

### How do I download every institutional holdings filing for a whole month in one bulk file instead of querying page by page?

Use the bulk holdings endpoint `/bulk/form-13f/holdings/YEAR/YEAR-MONTH.jsonl.gz`, substituting the year and month you want, for example `/bulk/form-13f/holdings/2024/2024-01.jsonl.gz` for January 2024. This returns a gzip-compressed JSONL file containing the holdings data of every 13F filing published that month, grouped by the filing's `filedAt` date.

Each line in the decompressed file is a standalone JSON object for one filing, carrying its accession number (`accessionNo`), filing manager CIK (`cik`), company name (`companyName`), and full `holdings` array. This format suits large-scale processing without paging through the search endpoint.

```bash
https://api.sec-api.io/bulk/form-13f/holdings/2024/2024-01.jsonl.gz?token=YOUR_API_KEY
```

### How can I check programmatically which monthly bulk files are available and when each was last refreshed?

Use the bulk index endpoint `/bulk/form-13f/holdings/index.json`, which returns a JSON array listing every available monthly holdings file. Each entry gives the file path in `key`, for example `2025/2025-03.jsonl.gz`, the timestamp of the file's last update in `updatedAt`, and the file size in bytes in `size`.

Reading this index lets a program discover which year-month files exist and detect when a specific file was last refreshed before deciding whether to download it. The bulk files and this index are updated once daily, reflecting filings published the previous day.

```bash
https://api.sec-api.io/bulk/form-13f/holdings/index.json?token=YOUR_API_KEY
```

### How do I page through more than 50 matching filings to retrieve a complete result set?

Use the `/form-13f/holdings` endpoint with the `from` and `size` parameters. The `size` parameter caps a single response at 50 filings, so to retrieve more, keep `size` at 50 and increase `from` by 50 on each subsequent request, requesting positions 0, 50, 100, and so on until no further results are returned.

The `from` value cannot exceed 10,000, which is also the maximum number of filings reachable for one query. If a query matches more than 10,000 filings, narrow the search universe so each query returns fewer matches, for example by adding a `filedAt` date-range condition to iterate month by month and paginating within each month separately.

```json
{
  "query": "filedAt:[2020-01-01 TO 2020-01-31]",
  "from": 50,
  "size": 50,
  "sort": [{"filedAt":{"order":"desc"}}]
}
```

### How can I rank the largest institutional managers by total portfolio value for a given reporting quarter?

Use the `/form-13f/cover-pages` endpoint, which carries each filing’s headline portfolio size without the full position list. Filter on the reporting period (`periodOfReport`) so it equals the quarter-end date you are studying, for example `2024-09-30` for the third quarter of 2024, and sort the results in descending order by the total dollar value of the portfolio (`tableValueTotal`). The managers with the largest portfolios then appear at the top.

Each cover page identifies the manager by name (`filingManager.name`) and by its SEC identifier (`cik`), and reports the portfolio size in `tableValueTotal` alongside the number of disclosed positions in `tableEntryTotal`. Because a single response is capped at 50 cover pages, page through the ranking by increasing the `from` offset by 50 until you have collected as many of the top managers as you need.

```json
{
  "query": "periodOfReport:2024-09-30",
  "from": 0,
  "size": 50,
  "sort": [{"tableValueTotal":{"order":"desc"}}]
}
```

### How can I check whether a fund's stated portfolio totals match the figures it actually reported on the filing, to spot reporting discrepancies?

Use the `/form-13f/cover-pages` endpoint, which exposes each filing's portfolio totals in two parallel forms. The total dollar value carries a normalized figure (`tableValueTotal`) and the figure exactly as the manager entered it on the filing (`tableValueTotalAsReported`), and likewise the number of disclosed positions carries a normalized count (`tableEntryTotal`) and the count as the manager reported it (`tableEntryTotalAsReported`). To spot a reporting discrepancy, retrieve the cover page for the filing and compare `tableValueTotal` against `tableValueTotalAsReported`, and `tableEntryTotal` against `tableEntryTotalAsReported`.

When the normalized and as-reported values for a filing disagree, the manager's stated summary does not line up with the figures derived from the holdings information table, which can point to a rounding choice, a unit error, or an omitted position. You can target a specific filing by filtering on its accession number (`accessionNo`), or scan a manager's history by filtering on the filing manager CIK (`cik`) and reviewing each returned cover page.

```json
{
  "query": "accessionNo:\"0001398344-24-020966\"",
  "from": 0,
  "size": 50
}
```
