SEC Filings Have a Free JSON API — Pull Any Company's 10-Ks, 8-Ks and Insider Trades Without a Key

The SEC provides a free JSON API for accessing financial data, including 10-Ks, 8-Ks, and insider trades, without requiring a key or authentication. This can be achieved by querying the SEC's endpoints using the Central Index Key (CIK) and following specific curl commands. It's essential to include a valid User-Agent and stay within the 10 requests/second fair-access ceiling. This allows developers to access a vast amount of financial data for free, making it a valuable resource for various applications.
