How this service works
List the VIN manufacturer prefixes (WMIs) registered for a manufacturer name such as Honda, with country and vehicle type.
Output
A JSON object containing an array of WMI entries, each with the 3-character WMI code, associated country, vehicle type, and manufacturer name. Also includes total count of matching WMIs, number shown, list of distinct countries and manufacturers, the query string used, data source info, timestamp, and an optional summary. May include degraded-mode warnings if the data source is partially unavailable.
Example use cases
Verifying manufacturer origin by WMI
“Show me all WMI codes registered to Toyota and tell me which countries they manufacture in — I want to know if they have US-based manufacturing based on the VIN prefix.”
Building a VIN decoder reference table
“Can you pull all the WMI prefixes for General Motors, up to 50 of them, so I can build a reference table that maps each prefix to its country and vehicle type?”
Researching EV manufacturer footprint
“What World Manufacturer Identifier codes are registered to Tesla and what vehicle types do they cover?”
Technical details
Endpoint
GEThttps://vehicle-vin.x402tookit.com/manufacturer-wmis?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate all WMI codes belonging to a named manufacturer — e.g. to build lookup tables, verify manufacturing origin by country, or understand which prefixes a brand uses across vehicle types. It complements the reverse lookup endpoint (WMI→manufacturer) by going from name to prefix. Prefer this over decoding a specific VIN when the goal is a comprehensive list rather than decoding a single vehicle.
Side effects
- Manufacturer name not found — returns empty WMI array with total=0
- Ambiguous name matching too many manufacturers — returns up to the limit with a summary note
- Degraded mode — upstream NHTSA data unavailable, returns partial or cached results with degraded=true
- Missing required 'name' query parameter — returns 400-level error
- Limit out of range (outside 1-100) — may return default of 25 or a validation error
