How this service works
Decode a 3-character World Manufacturer Identifier or 6-character low-volume identifier through the official NHTSA vPIC API.
Output
Returns a JSON object with the queried WMI string, a count of matched manufacturers, and an array of manufacturer records each containing manufacturer_name, make, and vehicle_type fields, along with a success flag.
Example use cases
Identify manufacturer from VIN prefix
“I have a VIN that starts with 'WVW' — can you decode that WMI and tell me which manufacturer and vehicle type it corresponds to according to NHTSA?”
Validate WMI in used-car listing
“This used car listing shows a VIN starting with '5YJ'. Can you decode that 3-character WMI through NHTSA to confirm who the manufacturer is and what type of vehicle it should be?”
Enrich fleet dataset with manufacturer info
“I have a batch of WMI codes like '1FT', 'JHM', and 'SAL' — can you look up each one through the official NHTSA WMI decoder and tell me the manufacturer name and make for each?”
Technical details
Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/wmi_decodeWhen to prefer
Use this endpoint when you need to identify the manufacturer behind a specific WMI prefix extracted from a VIN, or when verifying vehicle origin from first-party NHTSA data. Prefer this over full VIN decode when you only have the first 3 characters or need lightweight manufacturer-only lookups. Best for automotive data enrichment, fraud detection on VINs, and fleet management pipelines where manufacturer identity is the key need.
Side effects
- Invalid or unrecognized WMI returns empty manufacturers array with count of 0
- WMI shorter than 3 characters or longer than 6 characters may return an error or no results
- NHTSA upstream API unavailability causing timeout or 5xx response
- Non-alphanumeric characters in WMI may cause malformed request
