CongressInvests vs SEC EDGAR Data

CongressInvests tracks U.S. congressional stock trades from official Senate EFD and House Clerk disclosures, refreshed every six hours, with per-ticker trade history, a global feed, and a Pro-only AI-generated trend narrative (sentiment plus notable member patterns, cached 24 hours per ticker). The core REST API is keyless for up to 100 requests/day; a $29/month Pro plan adds an X-Api-Key header for webhook alerts, the AI trend endpoint, and higher limits. It ships official Python and Node.js SDKs and markets itself against paid-only competitors like QuiverQuant and Unusual Whales.

SEC EDGAR's data.sec.gov REST APIs serve JSON-formatted company filing histories and XBRL financial-statement facts (10-K, 10-Q, 8-K, and more) extracted from filings submitted to the U.S. Securities and Exchange Commission. No authentication or API key is required, but the SEC's fair-access policy requires a descriptive User-Agent header identifying the requester and caps traffic at 10 requests per second — requests without one are rejected with a 403. A live probe confirmed CORS is enabled (Access-Control-Allow-Origin: *) once that header is set.
