x402-gateway

Pay-per-lookup data for AI agents. Authoritative Swedish company and vehicle data, paid per call in USDC on Base via the x402 protocol. No account, no contract, no API key — HTTP 402 is the whole onboarding.

payments: on (eip155:84532)MOCK MODE — all data is fixture data, no live sources connected

How it works

GET any paid endpoint → you get 402 Payment Required with payment instructions.
Your x402 client (e.g. @x402/fetch) signs a USDC payment and retries with the PAYMENT header.
The gateway verifies, serves the data, then settles on-chain. Cache hits are instant.

Free endpoints: /api/v1/catalog, /api/v1/se/company/schema, /api/v1/se/vehicle/schema — inspect shapes before paying.
