## Authentication

Send the API key either as a header or as a query parameter. The header is preferred; the query parameter exists for cases where a header cannot be set, such as opening a URL directly in a browser.

Authorization: required header

The API key on its own. Do not prefix it with Bearer or any other word.

Example `Authorization: YOUR_API_KEY`

token: optional query parameter

The API key, appended to the URL. Use this only when a header is not possible.

## Request body

A JSON object. Content-Type must be application/json.

query: required string

The search expression in Lucene syntax, written as field:value. Every field listed under Searchable fields can be used, combined with AND, OR, NOT, ranges and wildcards.

Example `issuerInfo.issuerTicker:TSLA`

from: string, Maximum 10000

Index of the first result to return, used for pagination. Increment by the value of size to page through results.

Default `"0"`

size: string, Maximum 50

Number of Form 144 filings to return in one response.

Default `"50"`

sort: array of object

Sort order. Each item maps one field to an order object, for example [{ "filedAt": { "order": "desc" } }].

Default `[{ "filedAt": { "order": "desc" } }]`

Either asc or desc.
