The official source of U.S. regulatory filings. EDGAR provides free public access through its web portal, JSON data APIs, and structured RSS feeds (updated every 10 minutes). Developers can use the APIs on data.sec.gov for submissions and XBRL datasets, while filers use separate EDGAR Next APIs that require tokens. No email alerting is provided—RSS is the only push channel. Automated access must respect fair-use guidelines, including a descriptive User-Agent.
