# NHTSA VIN Decode (Single) — x402

> NHTSA VIN Decode (Single) — x402 is a paid API for AI agents from x402-service-production-e242.up.railway.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-28).

Decodes a single 17-character VIN using the NHTSA vPIC database to return vehicle spec data including make, model, year, trim, engine, transmission, drivetrain, GVWR, and plant country.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 nhtsa-vin-decode-single-x402-86813718
```

Example prompt: Can you decode the VIN 1HGCV1F34LA123456 and tell me the make, model, year, trim, engine, and drivetrain?

## When to prefer this

Use this endpoint when you need official factory specification data for a single vehicle and have its VIN. Prefer it over the batch endpoint for one-off lookups. Note that this returns spec data only — for accident, title, or odometer history, use a commercial vehicle history service. For NHTSA recall and safety data specifically, use the sibling safety report endpoint.

## Known failure modes

- Invalid VIN format (not 17 characters or contains invalid characters) — returns error
- VIN not found in NHTSA vPIC database — may return empty or partial fields
- Partial decodes for older or non-US vehicles where NHTSA data is incomplete
- Network timeout or upstream NHTSA API unavailability

## How this service works

Single VIN decode via NHTSA vPIC: make, model, year, trim, engine, transmission, drivetrain, GVWR, plant country. Spec data only -- no accident/title/odometer history.

## Output

A JSON object with structured vehicle spec fields: make, model, year, trim, body class, drivetrain, transmission type, GVWR class, plant country, and a recalls array. Does not include accident history, title info, or odometer data.
