  "description": "US congressional stock trades made agent-callable — the Senate and House STOCK Act disclosures that retail traders track (the 'trade like Congress' signal behind ETFs like NANC/KRUZ), served as a pay-per-call x402 endpoint instead of a human dashboard. Returns recent disclosed trades across both chambers (member, party district, ticker, buy/sell, dollar-amount range, transaction + disclosure dates, owner), a by-ticker lookup (who in Congress traded a given symbol), and an aggregate 30-day buy/sell signal (most-bought / most-sold tickers). Data is lagged by design (STOCK Act allows up to 45 days to disclose). $0.05 in USDC on Base via x402. Source: FMP Senate/House disclosure feeds, self-indexed.
