finance.sec-filings

Recent SEC EDGAR filings for a US publicly-traded company by stock ticker. Resolves ticker → CIK via SEC's company_tickers.json, then fetches the company's submissions index from data.sec.gov. Returns company metadata (name, CIK, SIC industry classification, exchanges, fiscal year-end, state of incorporation) plus filings with form type, filing date, report date, accession number, primary-document URL, and filing-index URL. Filter to one form type (10-K, 10-Q, 8-K, 4, 13F-HR, SC 13G, S-1, etc.) via formType param. Default 20 results, max 100. Backed by SEC.gov; underlying filings are public-domain US government records.

Code samples

cURLbash

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/finance/sec-filings?ticker=example&formType=example&limit=20'

# 2. Sign + retry with PAYMENT-SIGNATURE:

  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):

#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/finance/sec-filings?ticker=example&formType=example&limit=20'
