  title: SEC API (sec-api.io) REST Extractor Full-Text Search API
  description: 'REST surface of SEC API (sec-api.io), a commercial developer platform that turns the U.S. SEC EDGAR system into fast, queryable APIs. Covers 18+ million filings back to 1993 across 400+ form types. This document models the core REST endpoints - Filing Query, Full-Text Search, XBRL-to-JSON, Extractor, Insider Trading (Form 3/4/5), and Form 13F institutional holdings. The real-time Filing Stream API is a WebSocket surface and is modeled separately in asyncapi/sec-api-asyncapi.yml.

    Authentication is a single API token, obtained from your sec-api.io account. Pass it either as an `Authorization: YOUR_API_KEY` header or as a `?token=YOUR_API_KEY` query parameter. Endpoints, request shapes, and parameters were grounded against the live sec-api.io documentation on 2026-07-11.'
