I made a Congress Trading Tracker API

By law, members of Congress have to publicly disclose their stock trades within a matter of weeks. I built an API that turns those disclosures into something you can actually query and build on, instead of digging through messy filings by hand.

The API serves stock trades by members of Congress (not the Senate at this time, as they have a scary prompt warning against using their data commercially), all the way back to 2020 - and updated every 6 hours.

Available Endpoints

• Querying latest trades made
• Filtering by politicians / tickers / buy / sell
• Most-traded tickers
• Reconstructed politician portfolio++

The API can be queried directly or hooked up to a dashboard, trading apps, etc. Basically the same as Unusual Whales, Capitol Trades or Autopilot - just free and you have access to the structured data to do with it as you'd like.

Conflict-of-Interest Detection

There's also a possible conflict-of-interest endpoint. Trades get automatically cross-referenced against each politician's committee assignments, so you can surface cases where, say, someone on a defense-oversight committee is trading defense contractor stock.

Pricing

The basic tier is totally free, and I would be super happy to hear your thoughts and feedback!
