How this service works
US federal bills from Congress.gov (Library of Congress). Keyword search (q) runs over the 250 most recently updated bills of a Congress, since the API has no full-text search; each match gets its sponsor, status and latest action. A bill number (bill=hr1234-119) returns its cosponsor count, committees and up to 30 actions. Public domain.
Output
Returns a JSON object with the search query metadata, total matching bills found, a list of bill results (each with bill number, title, Congress.gov link, status, sponsor name/party/state, cosponsor count, introduction date, policy area, and latest legislative action), plus how many bills were scanned and a timestamp.
Example use cases
Policy researcher tracking AI legislation
“Find me all recent bills in the 119th Congress that mention 'artificial intelligence' in the title — I want to see who sponsored them and where they are in the process.”
Journalist checking bill status by ID
“Can you look up bill hr1234-119 for me and tell me its current status, who sponsored it, and what the latest action was?”
Lobbyist monitoring healthcare legislation
“Search the current Congress for bills with 'Medicare' in the title — give me up to 10 results showing the sponsor, party, and most recent legislative action.”

Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/congress?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, pay-per-call access to US Congressional bill data without an API key or signup — ideal for agents that need to look up specific bills by ID or search titles by keyword within the current or recent Congresses. Prefer this over direct Congress.gov API calls when you need x402 micropayment integration with no authentication overhead.
Side effects
- Keyword search only covers the 250 most recently updated bills — older or less-active bills may not appear
- No full-text search supported — query words must appear in the bill title only
- Invalid bill ID format returns an error or empty result
- Congress number out of range (below 93 or above current) may return an error
- Limit parameter outside 1-25 range may be rejected or clamped
