## 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 tanod-web-vin-decoder-2bd2d121 -d '<json body>'
```

Example prompt: Can you decode the VIN 1HGCM82633A004352 and tell me the make, model, year, engine, and transmission for that vehicle?

## When to prefer this

Choose this endpoint when you need structured, authoritative vehicle data decoded from a VIN, especially for US-market vehicles where NHTSA data is most complete. It is backed directly by the NHTSA vPIC database, so it is the most reliable source for US vehicle specs, recall linkage, and manufacturer information. Prefer this over generic web search when you need machine-readable structured fields (engine cylinders, GVWR class, plant location) rather than prose descriptions.

## Known failure modes

- 422 error if VIN is not exactly 17 characters or contains invalid characters (I, O, Q)
- Partial decode for non-US-market vehicles — some fields may be null
- Check digit warning (not an error) if the 9th position digit is incorrect for North American VINs
- VIN not found in NHTSA database returns found:false with minimal data
- Network or upstream NHTSA API unavailability may cause service errors

## How this service works

Web tools: search, page to Markdown or screenshot, company profile and jobs, sitemaps, RDAP, IP.

## Output

Returns a JSON object with decoded vehicle fields including make, model, model year, trim, series, body class, drive type, fuel type (primary and secondary), engine details (cylinders, displacement, horsepower, configuration, model), transmission type, doors, GVWR class, manufacturer name, plant location (city, state, country), NHTSA error code and text, check digit validity, any warnings, and whether the result was cached. Also includes a suggested VIN if the submitted one had correctable errors.
