Federal securities laws require insiders, including officials, directors, and those holding more than 10% of a company's securities, to report their purchases, sales, and holdings. The API endpoint gives comprehensive information about each of the transactions. The data is available for a few thousand US companies. There is a limit of 50 records per API call.
