SEC.gov (EDGAR)

sec.gov

Editor’s pick Hands-on review

Official U.S. SEC portal for free public access to EDGAR filings and related data tools. Public REST APIs on data.sec.gov deliver JSON and require no auth/API keys, but automated access must comply with SEC privacy/security policy, uses a declared User-Agent header, and is rate-limited (SEC states a max of 10 requests/second). data.sec.gov does not support CORS. SEC also links to a separate EDGAR Public Dissemination Service (PDS) subscription feed (managed by a contractor).
