This tool resolves a ticker, company name, or CIK and pulls the recent filing list direct from EDGAR with links into each filing.
Where does the data come from?
The SEC EDGAR submissions API at data.sec.gov. Worker proxies the request because SEC requires a User-Agent header identifying the caller (legal requirement under data.sec.gov terms). Filings appear in EDGAR within minutes of acceptance; this tool reflects that real-time state.
