SEC EDGAR filings API: find 10-K, 10-Q and 8-K documents

Find an annual report

Set STRALE_API_KEY to your API key, then run:

curl -X POST https://api.strale.io/v1/do \
  -H "Authorization: Bearer $STRALE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "capability_slug": "sec-edgar-filings",
    "inputs": { "ticker": "AAPL", "form_type": "10-K", "limit": 1 },
    "max_price_cents": 3
  }'

Use 10-Q for quarterly filings or 8-K for current reports. The form filter is exact: 10-K does not also select 10-K/A. Omit form_type to include all recent forms. limit accepts 1 to 50 and defaults to 20.

Use a CIK when needed

Replace ticker with "cik":"320193" to look up the same filer by its SEC Central Index Key. A CIK can have up to ten digits, including leading zeros. If both inputs are supplied, CIK takes priority. Use it when a filer is missing from the SEC ticker index.

Read the links and dates

In the response's output, filings holds the matching records and returned gives their count. Each record can include a document url, an index_url, an accession number, a filing_date and a report_date. The filing date and the period or event date are different; the report date may be absent.

Open the document URL to read the source. The tool does not parse the filing’s financial statements, return XBRL facts or monitor filings on a schedule. Your application decides when to call and can use accession numbers to avoid processing the same filing twice.

Understand the search window

Only the recent filings in the SEC submissions response are searched. Older archive pages are not traversed, so a low result count or empty list is not evidence that no older filings exist. Use the returned edgar_url to explore the filer’s full history.

See SEC EDGAR Filings for all inputs, output fields and current limitations.
