In depth comparison

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).

Latest Filings provides a real-time listing of filings as they are submitted; SEC recommends Latest Filings + RSS for near-real-time access and notes EDGAR filing email alerts are not offered (RSS instead).
Mutual Funds Search supports searching funds/ETFs by name, series/class or contract IDs, ticker, or CIK, and links to prospectuses and proxy voting records; users can subscribe via RSS.
Developer access: data.sec.gov hosts RESTful JSON APIs for submissions history by company (submissions JSON includes names, exchanges and ticker symbols) and XBRL-derived data via companyconcept, companyfacts, and frames endpoints.
