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.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/sec-api: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
