Resolve an FCC ID (printed on US wireless/electronic devices) to the grantee — the manufacturer that holds the FCC equipment authorization. Pass fccId in any form (BCG-E3217A, BCGE3217A). Returns the grantee code, the product code, and the grantee company: name, city, state, country, and the date its grantee code was registered. Uses the FCC EAS Equipment Authorization Grantee Registrations open dataset, free and keyless — the "who made this device" lookup an agent reading a label off hardware cannot do natively. (Per-product RF detail — frequencies, equipment class — is not in the open dataset and is out of scope.)
/api/gov/fcc-idPAYMENT-SIGNATURE.The fcc id API is a pay-per-call gov endpoint built for AI agents and autonomous software. Resolve an FCC ID (printed on US wireless/electronic devices) to the grantee — the manufacturer that holds the FCC equipment authorization.
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 fcc id 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.
