​
SEC Filing Download & CDN API

EDGAR’s 10 requests-per-second rate limit makes bulk document retrieval painful. SEC API gives you accession-number download and export endpoints so you can fetch filing documents through the same authenticated API surface you use for filing search.

​
Capabilities

API-first downloads

Download filing documents by accession number without screen-scraping EDGAR archive pages.

Export workflows

Use export endpoints when you need filing artifacts packaged for downstream storage or analysis.

All document types

PDFs, HTML filings, XML/XBRL exhibits, and all associated documents for every filing since 1993.

Direct accession lookup

Pass an accession number and retrieve the filing document through a stable API route.

​
Quick start

Download a filing by accession number: 
curl -H "x-api-key: $SECAPI_API_KEY" \
  "https://api.secapi.ai/v1/filings/0000320193-24-000081/download" -o filing.html

{
  "accession_number": "0000320193-24-000081",
  "content_type": "text/html",
  "filename": "aapl-20240928.htm",
  "requestId": "req_..."
}
Export a filing package for downstream processing: 
curl -H "x-api-key: $SECAPI_API_KEY" \
  "https://api.secapi.ai/v1/filings/0000320193-24-000081/export"
