Overview

SEC EDGAR is the US Securities and Exchange Commission's full-text search across public company filings. For any US-listed company, EDGAR provides authoritative 10-K (annual report), 10-Q (quarterly), 8-K (current event), and proxy or insider filings.

When to Choose It

• Choose it for US company research, especially financial history, risk factors, regulatory disclosures, and management discussion.
• Choose it when a query implies a publicly traded US company, such as a ticker, "SEC filing", "10-K", or "earnings report".
• Avoid it for general tech news, academic papers, or non-US companies.

How To Search

• api_search queries https://efts.sec.gov/LATEST/search-index?q=<query> and maps hits.hits[*]._source into filing evidence. Filing URLs are synthesized from ciks[0] and adsh to point at the SEC Archives index page for the exact filing.

Known Quirks

• SEC enforces a User-Agent policy. Every request must carry a contact string or the endpoint may effectively block access.
• The search endpoint returns filing metadata only, not filing-body excerpts. Snippets are synthesized from form type and filing dates.
• Coverage is limited to SEC-registered filers, so pure non-US companies are out of scope unless they file with the SEC.

Quality Bar

• Evidence items have non-empty title and url.
• No crash on empty or malformed API response.
• Source channel field matches the channel name.
