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 API contracts indexed 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
