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.
