SEC API
SEC API (sec-api.io) is a commercial developer platform that turns the U.S. Securities and Exchange Commission's EDGAR system into a fast, queryable REST and real-time streaming API. It covers 18+ million filings back to 1993 across 400+ EDGAR form types, with a Lucene-based Filing Query API, a Full-Text Search API over filing bodies and exhibits since 2001, an XBRL-to-JSON financial statement converter, a section Extractor for 10-K/10-Q/8-K, and structured datasets for insider trading (Form 3/4/5), institutional holdings (Form 13F), 13D/13G, Form D, Form ADV, IPOs, and more. A real-time Filing Stream API pushes newly published filings to clients over a WebSocket connection as soon as they hit EDGAR. Access is via a single API token passed as an Authorization header or a token query parameter.
SEC API publishes 7 APIs on the APIs.io network, including Filing Stream API, Extractor API, Filing Query API, and 4 more. Tagged areas include SEC Filings, Regulatory Filings, EDGAR, Financial Data, and Compliance.
The SEC API catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
SEC API’s developer surface includes authentication, documentation, and 7 more developer resources.
