Search currently-active FARA (Foreign Agents Registration Act) registrants by name. Pass a company or person name; returns whether the entity is a registered foreign agent (isRegisteredForeignAgent), a single KYB-safe bestMatch (null below medium confidence — no false positives), and scored candidate matches with registration number, registration date, city/state, and a 0-1 match score + confidence (high/medium/low). FARA registration is a US disclosure status (an agent acting for a foreign principal), not wrongdoing. Authoritative DOJ FARA eFile data, free and keyless — the foreign-agent check a compliance or procurement agent cannot derive from training.
/api/gov/foreign-agentsPAYMENT-SIGNATURE.The foreign agents API is a pay-per-call gov endpoint built for AI agents and autonomous software. Search currently-active FARA (Foreign Agents Registration Act) registrants by name.
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 foreign agents 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.
