Look up or list US Congressional hearings via Congress.gov. Pass congress + chamber + jacketNumber to fetch a single hearing with full detail (title, dates, committee, transcripts/recordings if available). Or filter list by congress + chamber, with optional date range. Hearings cover committee testimony from the executive branch, subject experts, and stakeholders — primary-source material for oversight + policy research.
/api/gov/congress-hearingPAYMENT-SIGNATURE.The congress hearing API is a pay-per-call gov endpoint built for AI agents and autonomous software. Look up or list US Congressional hearings via Congress.gov.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in congress hearing data source for an agent tool-use loop, an MCP host, or a backend that needs gov data on demand without onboarding to yet another vendor portal.
