Every disclosed House & Senate stock trade from official STOCK Act filings — as a free JSON REST API and a focused MCP server. Unlike other free trackers, we include per-trade performance (price at the trade vs latest, % move since). Open CORS, generous limits.
Base URL: https://bargo.ai/free-apis/congress/v1. No key required for read endpoints (rate-limited); a free key raises the limits and unlocks MCP.
Global feed across all tickers, newest first. Query: limit (≤100, or ≤250 with a key), page, ticker, member, chamber, type, from/to (YYYY-MM-DD).
All trades for one stock symbol, newest first. Supports from/to, limit, page.
Members ranked by trade count, with buys/sells and last-trade date.
One member's full trade history + a performance summary.
Totals + most-traded tickers (last 90 days).
Liveness + data freshness.

Filings carry a legal lag of up to ~45 days, so read this as recent-weeks activity, not real-time.
