https://x402-filings.datalayer.workers.dev/v1/safety/vin-decode

answers 402

Decode any 17-character VIN into the vehicle it describes: make, manufacturer, model, year, series, body class, drive type, engine, fuel, transmission and assembly plant. NHTSA returns 140 mostly-empty fields; this strips the blanks, promotes the ones that matter and reports whether the check digit validated.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
