How this service works
The checks your agent runs before it acts: verify a bank account, a phone number, a law in force, the weather or a vehicle — computed from official sources, with provenance in every response. You only pay for answers.
Output
Returns decoded vehicle attributes derived from the 17-character VIN: the World Manufacturer Identifier (WMI), country and region of assembly, model year, check digit validity status, and any additional deterministic attributes sourced from the official NHTSA vPIC tables.
Example use cases
Verify VIN before private sale
“I'm about to buy a used car from a private seller and they gave me the VIN 2T1BURHE0JC034761. Can you decode it and tell me who made it, where it was built, what year it is, and whether the VIN itself checks out as legitimate?”
Validate listed vehicle VIN accuracy
“We have a car listing on our platform with VIN 3VWFE21C04M000001 and I want to make sure the manufacturer, country of origin, and model year in the listing actually match what the VIN says — can you run a decode and flag any mismatches?”
Confirm insured vehicle origin details
“Before we finalize this insurance policy, I need to confirm the build details on the vehicle — the VIN is 5YJSA1DG9DFP14661. Can you tell me the manufacturer, where it was assembled, the model year, and whether the check digit is valid so we know it's a real VIN?”
Technical details
Endpoint
POSThttps://api.invoket.com/vehicle/vin/decodeWhen to prefer
Use this endpoint when you need a fast, keyless, pay-per-call VIN decode against official NHTSA data without account setup. Ideal for one-off lookups, agent workflows needing manufacturer/origin/year validation, or when you want deterministic offline-style decoding without a subscription. Prefer the sibling 'consolidated vehicle report' endpoint if you also need recall data or emissions info in a single call.
Side effects
- Invalid or malformed VIN (not 17 characters) — returns validation error
- VIN with unsupported or unknown WMI not in NHTSA vPIC tables — partial or empty decode
- Check digit mismatch — flagged in response but not necessarily a hard failure
- Network or payment failure via x402 — call not completed, no charge
