finance.company-facts

Curated XBRL financial metrics for a US public company by stock ticker. Pulls SEC EDGAR's companyfacts JSON (per-CIK XBRL filings) and extracts a top-line set of ~15 financial metrics with their most recent annual + quarterly values. Each metric returns: end date, start date (or null for balance-sheet snapshots), value, fiscal year/period, originating form (10-K/10-Q), and filed date. Available metric keys (pass any comma-separated subset via the metrics param, or omit to get all): revenue, grossProfit, operatingIncome, netIncome, eps, epsDiluted, rdExpense, totalAssets, totalLiabilities, stockholdersEquity, cash, longTermDebt, operatingCashFlow, capex, sharesOutstanding. Backed by SEC.gov; underlying data is public-domain US government records.

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/finance/company-facts?ticker=example&metrics=example&annualLimit=4&quarterlyLimit=4'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/finance/company-facts?ticker=example&metrics=example&annualLimit=4&quarterlyLimit=4' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

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