Members of Congress must publicly disclose their stock trades under the STOCK Act. The Wealthnow API returns those disclosures as structured JSON, filterable by ticker, with the member's party and chamber, the side of the trade and whose account it was. The same data is a tool on the Wealthnow MCP server, so Claude or ChatGPT can answer congress-trading questions directly.
What does the congress trading endpoint return?
GET /api/v3/intel/congress returns congressional trades with an optional ticker filter. Each trade includes the side (buy, sell or exchange), party and chamber codes, whether the filer is a member of Congress (executive-branch filers are marked), and the owner of the account (self, spouse, joint or child) where the disclosure states it. Rows from the default feed also carry the asset type from the disclosure (stock, option, government security and more), with option type, strike and expiry where the source gives them.

"https://firm.wealthnow.io/api/v3/intel/congress?ticker=NVDA&limit=50"Can I look up a specific member of Congress?
GET /api/v3/intel/politicians returns the full House and Senate roster with disclosed trade counts and the identifiers you need to pull one member's trades. Treat the trade count as the source's running total, not recent activity.
How fresh and how complete is the data?
Two sources sit behind the endpoint. The default is a cross-ticker feed of new disclosures; the reported date there is the day the source recorded the disclosure, which can trail the filing date by one to three days. The second, provider=alternative_data, is a warehouse archive that holds trades from May 20, 2025 onward, with earlier history for some tickers. Responses say where the archive begins (data_from, history_floor, coverage_note), so your app never has to guess. Disclosures themselves arrive late by design: the STOCK Act gives members up to 45 days after a trade to report it. How the public tracker cleans the data is on the methodology page.
How do AI agents use it?
On the MCP server at https://mcp.wealthnow.io/mcp the endpoint is the intel_congress tool. Connect Claude, ChatGPT, Cursor or Codex with OAuth sign-in and ask, for example: "Using Wealthnow, which members of Congress disclosed trades in NVDA this year, and on which side?" Setup: connect your AI client.
