Vin lookupVehicle dataAutomotiveWheel fitmentVehicle specifications

AUTO411 is a VIN lookup and vehicle data API for AI agents. Resolve a full VIN or year, make and model to a validated vehicle identity and configuration, then retrieve structured JSON vehicle specifications and available wheel and tire fitment including OEM tire sizes, bolt pattern / PCD, center bore, offset and thread / lug size. Returns MATCHED_SINGLE, NEEDS_IDENTITY or NO_MATCH rather than guessing ambiguous vehicles.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
