Kapitol.ai Congress Trading API

About

A first-party REST API for U.S. Congress stock trades. We read the official House Clerk and Senate disclosure sources directly, so coverage spans every filer, both chambers, and scanned paper filings. Each record carries the full filing: asset descriptions, exact amount ranges, filer comments, transaction subtypes, and spouse/dependent trades, with history back to 2012 and new filings within minutes. Free to start.
