Frequently Asked Questions

  • Yes, but you must have a premium subscription. Commercial use of the Insider Trading API is not permitted on the free tier. See our pricing page to choose a plan that fits your needs.
  • Sign up for a free account to instantly get your API key, then pass it in the X-Api-Key header on every request. The documentation above includes ready-to-run examples in cURL, Python, JavaScript, Node.js, and more.
  • Your API requests will simply be denied once you hit your monthly quota — you will never be charged more than the plan you signed up for. To increase your quota, you can upgrade your plan any time on our pricing page.
  • The API responds with a standard HTTP status code and a JSON error message describing the problem. See our error codes reference for the full list of codes and how to resolve each one, or contact support if you need help.
  • The API offers /v1/insidertransactions to search and filter individual transactions across companies and insiders, /v1/insiderdetails to pull detailed transaction history for a single insider (by exact name), and /v1/insiderslist to list every insider for a company along with their current share holdings. The latter two are premium only, and you can explore the full Finance catalog on the APIs page.
  • All data comes from SEC insider trading filings, specifically Form 3, Form 4, and Form 5, and each record includes the original sec_filing_url and accession_number so you can trace it back to the source. For raw filing access you may also find our SEC API useful.
  • On the /v1/insidertransactions endpoint you can combine optional filters such as ticker or cik for the company, form_type (3, 4, or 5), transaction_type, insider_type (director, 10_percent_owner, or officer), date ranges via min_transaction_date and max_transaction_date, and dollar thresholds with min_transaction_value and max_transaction_value. To resolve a company ticker first, see the Ticker API.
  • Each transaction returns details such as insider_name, insider_position, transaction_code, transaction_type, transaction_price, shares, transaction_value, and holdings before and after the trade via pre_transaction_shares and remaining_shares. To pair this with market pricing, check out the Stock Price API.
