## 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 polyform-vin-decoder-safety-recall-lookup-b2d9e067
```

Example prompt: Can you decode the VIN 1HGBH41JXMN109186 and tell me everything about the vehicle — specs, trim level, and whether it has any open NHTSA safety recalls?

## When to prefer this

Choose this endpoint when you need authoritative, federally-sourced vehicle data for US-market vehicles — especially when recall status matters for safety, compliance, or purchase decisions. Prefer this over third-party VIN decoders when accuracy and regulatory authority are required. If you also need a buy/avoid recommendation or fuel cost estimate, consider the sibling advisory endpoint instead.

## Known failure modes

- Invalid or malformed VIN returns an error response
- VIN not found in NHTSA database (e.g. non-US-market vehicles) returns no results
- Non-US VINs may decode partially or fail
- Temporary NHTSA API unavailability causes upstream errors
- VINs for very new or very old vehicles may have limited recall data

## How this service works

Decode any US-market VIN to full vehicle specs and list open safety recalls. Source: US NHTSA (federal, authoritative). JSON.

## Output

A JSON object containing decoded vehicle specifications (make, model, year, trim, engine, drivetrain, and other NHTSA-sourced attributes) along with a list of any open federal safety recalls for that specific vehicle, sourced authoritatively from the US NHTSA database.
