Mapping API
The Mapping API resolves a ticker symbol, CIK, CUSIP or company name to a set of standardized company details. The API is used for mapping between different identifiers and company information and covers currently listed and delisted companies on US exchanges.
Company information includes a variety of identifiers and attributes, such as the ticker symbol, CIK, and CUSIPs, along with additional details like the exchange where the company is listed, its sector and industry, SIC code, headquarters location, security category, and the currency in which the security is traded.
API Endpoints
Mapping Endpoints
Seven Mapping API endpoints are available for mapping and retrieving company details by CIK, ticker, CUSIP, company name, exchange, sector, and industry. Each endpoint maps a specific identifier to company details and returns an array of companies matching the search criteria. For example, mapping a ticker to company details returns an array of listed and delisted companies that trade or traded under the ticker symbol.

Authentication
The Mapping API supports two authentication strategies. Either set your API key as Authorization header or attach your key as query parameter:
- Set as
Authorizationheader. Before making aGETrequest to any of the mapping endpoints, you need to set theAuthorizationheader toYOUR_API_KEY. - Set as query parameter. Example:
https://api.sec-api.io/mapping/cik/1318605?token=YOUR_API_KEY
In this case, performGETrequests to the endpointhttps://api.sec-api.io/mapping/cik/1318605?token=YOUR_API_KEYand not tohttps://api.sec-api.io/mapping/cik/1318605.
Response Format
Response format: JSON
Every API endpoint returns an array with companies matching your query. An array item has the following structure:
name(string) - the name of the company, e.g. Tesla Incticker(string) - the ticker symbol of the company.cik(string) - the CIK of the company. Trailing zeros are removed.cusip(string) - one or multiple CUSIPs linked to the company. Multiple CUSIPs are delimited by space, e.g."054748108 92931L302 92931L401"exchange(string) - the main exchange the company is listed on, e.g. NASDAQisDelisted(boolean) -trueif the company is no longer listed,falseotherwise.category(string) - the security category, e.g. "Domestic Common Stock"sector(string) - the sector of the company, e.g. "Consumer Cyclical"industry(string) - the industry of the company, e.g. "Auto Manufacturers"sic(string) - four-digit SIC code, e.g. "3711"sicSector(string) - SIC sector name of the company, e.g. "Manufacturing"sicIndustry(string) - SIC industry name of the company, e.g. "Motor Vehicles & Passenger Car Bodies"currency(string) - operating currency of the company, e.g. "USD"location(string) - location of the company's headquartersid(string) - unique internal ID of the company, e.g. "e27d6e9606f216c569e46abf407685f3"
