finance.insider-trades

Recent SEC Form 4 insider transactions for a US public company by ticker. Returns parsed transactions: insider name + relationship (director, officer/title, 10%+ owner), transaction date, SEC code (P=purchase, S=sale, A=grant, D=disposition, M=exercise, F=tax-withholding, G=gift), security title, shares, price/share, total USD value, post-transaction balance, direct vs indirect ownership. Each filing pulled separately and parsed from raw XML — bounded by limit (1-10, default 5). Backed by SEC.gov; underlying Form 4 filings are public records.

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/finance/insider-trades?ticker=example&limit=5'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/finance/insider-trades?ticker=example&limit=5' \
