Your sitting members of the US Congress for a location. Pass a US address (geocoded to its state + congressional district for you), or an explicit state (2-letter) with optional district number. Returns the current US House representative for that district plus the state's two US senators — each with full name, party, state/district, the Bioguide ID, DC office, phone, official website, and contact form. State-only returns just the two senators; territories/DC return their non-voting delegate (no senators). Bundled CC0 data (unitedstates/congress-legislators), refreshed periodically. Fills the gap after gov.district (which gives the district, not the people) — for civic lookup, advocacy, and constituent tooling.
/api/gov/representativesPAYMENT-SIGNATURE.The representatives API is a pay-per-call gov endpoint built for AI agents and autonomous software. Your sitting members of the US Congress for a location.
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 representatives 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.
