SEC EDGAR Submissions & Full-Text Search REST APIs

SEC EDGAR Submissions & Full-Text Search REST APIs is a rest api from U.S. Securities and Exchange Commission (SEC) providing stocks & equities data. The SEC's free, authoritative REST APIs on data.sec.gov and efts.sec.gov expose every public company's EDGAR filing history, structured XBRL financials, and full-text search across all filings. A Polymarket bot can poll these to detect 8-K earnings, guidance, and material events the moment they hit EDGAR — signal for equity/index outcome markets like "will TSLA/SPX close above $X."
