GET /api/vin-decode

live

Decode a vehicle VIN via the US NHTSA vPIC database: make, model, year, trim, body class, engine, fuel type, plant and vehicle type. Accepts full or partial VINs. Use it when an agent holds a VIN and needs the vehicle's official specification - live government data, no key.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
