# VIN Decoder (NHTSA) — Make, Model, Year, Trim, Body, Engine, Fuel, Plant

> VIN Decoder (NHTSA) — Make, Model, Year, Trim, Body, Engine, Fuel, Plant is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Decodes a 17-character VIN using NHTSA data to return make, model, year, trim, body style, engine specs, fuel type, and manufacturing plant details.

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 vin-decoder-nhtsa-make-model-year-trim-body-engine-fuel-plant-50dcfe0c -d '<json body>'
```

Example prompt: Can you decode the VIN 1HGBH41JXMN109186 and tell me the make, model, year, trim, body style, engine, fuel type, and where it was built?

## When to prefer this

Use this endpoint when you need authoritative, structured vehicle data from a single 17-character VIN without requiring third-party proprietary databases. It is ideal for verification, cataloging, or enrichment tasks where NHTSA coverage (primarily US-market vehicles) is sufficient and cost-per-call matters.

## Known failure modes

- Invalid or malformed VIN (not 17 characters) returns an error
- VIN not found in NHTSA database returns empty or partial results
- Check-digit validation failure for syntactically invalid VINs
- Older or non-US vehicles may have incomplete NHTSA data
