> Vehicle VIN Toolkit – WMI Lookup is a paid API for AI agents from vehicle-vin.x402tookit.com, paid per call via x402, $0.02/call, status down (last checked 2026-10-23).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vehicle-vin-toolkit-wmi-lookup-2401ecb4
```

Example prompt: Can you look up VIN prefix 1HG and tell me which manufacturer, make, country, and vehicle type it belongs to?

## When to prefer this

Use this endpoint when you have only the first 3 (or 6) characters of a VIN and need to identify the manufacturer, make, vehicle type, and country of origin without decoding the full VIN. It is faster and cheaper than a full VIN decode when manufacturer identity is all that is needed. Prefer this over full VIN decode endpoints when the complete 17-character VIN is unavailable or when enriching records that only carry a WMI prefix.

## Known failure modes

- Unknown or unregistered WMI returns null fields or a negative verdict
- Malformed WMI (not 3 or 6 characters) may result in an error or empty response
- Small-manufacturer 6-character WMIs may require the full 6-char prefix; 3-char lookup may return no match
- Data may be degraded or stale if the upstream NHTSA source is unavailable (degraded flag set to true)
- Payment failure (x402) results in request not being processed

## How this service works

Look up the manufacturer, make and vehicle type behind a 3-character VIN prefix (WMI), with region and country.

## Output

Returns a JSON object containing the WMI code, manufacturer name, common name, make, vehicle type, region, country, parent company, source URL, registration date, availability date, a summary verdict, and any degraded-data flags or disclaimer notes.
