Comparing tools? See Disclosed Capitol vs. Capitol Trades and vs. QuiverQuant — both cover whether each has a developer API.

What you can build

A real-time alert pipeline triggered by new STOCK Act filings.
Backtests of consensus picks — what would $10K have done if it followed every member of Congress who bought $NVDA above a confidence threshold?
A custom dashboard that surfaces committee portfolios alongside your own holdings.
Newsletter automation that pulls the latest disclosed trades for a watchlist of tickers or members and emails subscribers when something hits.
Research tooling for journalists, analysts, or fund operators that needs structured access to the raw filings without scraping the House and Senate disclosure portals.

Frequently asked questions

What does the Disclosed Capitol API give me access to?: Real-time disclosed congressional stock trades sourced from official U.S. House and Senate STOCK Act filings (PTRs and annual reports), structured as clean JSON. Endpoints cover per-member, per-ticker, per-committee, and recent-trades views.
Is there a free tier?: Yes. The free tier covers exploratory use and small projects. Pro adds higher rate limits, full historical coverage, and SLA. See pricing on the signup page.
How fresh is the data?: Disclosed Capitol ingests new STOCK Act filings on a continuous schedule throughout each trading day. Once a filing is parsed and verified, it's available through the API within minutes.
Can I redistribute or republish the data?: Underlying STOCK Act filings are public-record U.S. government disclosures. Disclosed Capitol's value-add (parsing, normalization, performance metrics, AI analysis) is licensed under the terms posted at /terms — attribution required for republishing aggregated outputs.
How do I get an API key?: Sign up for a free account and generate a key from the Account → API Keys panel. Pass it as a Bearer token in the Authorization header.
Is there a congressional trading API for congress stock trades?: Yes — the Disclosed Capitol API is a congressional trading API. It returns disclosed congress stock trades as JSON: query by member of Congress, by ticker, by committee, or pull the most recent filings. Each trade includes the transaction type, ticker, amount range, transaction date, and disclosure date, sourced from official STOCK Act filings. Start on the free tier at /developers.
Can I get politician stock trades through the API?: Yes. GET /politicians lists every tracked member with aggregate stats, and GET /politicians/{id}/trades returns that politician's full disclosed stock-trade history. Per-member performance fields (CAGR, alpha vs. the S&P 500) are included where enough enriched trades exist.
Does the API include both Senate and House trading data?: Yes — coverage spans both chambers. Every endpoint includes U.S. Senate and U.S. House STOCK Act disclosures (and executive-branch filers where available), so a single API key covers House trading data, Senate trading data, and cross-chamber views by ticker or committee.
