Overview

Bill Radar API overview

A clean JSON API over federal and state legislative intelligence — bills, regulations, legislators, search, and more.

The Bill Radar API gives you programmatic access to the same legislative intelligence that powers One Click Politics: bills across Congress and all 50 states, plus federal regulations, legislators, and search.

Conventions

  • All responses are JSON. List endpoints wrap results in a data array; detail endpoints return the object directly.
  • Every request must be authenticated with an API token (see Authentication & API keys).
  • Errors return { "error": { "message": "...", "status": 401 } } with the matching HTTP status.

What you can do

Search and read bills (with sponsors, votes, actions, text, committees, similar bills, and AI explainers); search and read regulations with their comment windows; look up legislators and run unified search; and react in real time with webhooks. Want access? Apply for an API key.
