SEC EDGAR full-text search API: access card
What is the EDGAR name-to-CIK resolver?
SEC EDGAR full-text search API is the full-text search over SEC filings — the standard way to resolve a company name to its CIK, published by US Securities and Exchange Commission. Coverage: United States (federal); scale: all EDGAR filings since 2001, according to the catalog manifest. In our data — the Aidenix Atlas catalog of verified sources — this endpoint was last probed on 2026-07-24 and returned HTTP 200. What the card gives you:
- The exact endpoint and a working request you can copy.
- Authentication and rate limits: none.
- The query keys the source accepts and the fields it returns, verified against the live endpoint.

Notes from the catalog recipe:
- Auth: none, but a descriptive User-Agent header is mandatory, according to the SEC fair-access policy.
