# NHTSA VIN Decoder (Offline)

> NHTSA VIN Decoder (Offline) is a paid API for AI agents from api.invoket.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Decodes any 17-character VIN into manufacturer, country/region of build, model year, check digit validity, and deterministic vehicle attributes using official NHTSA vPIC tables — no API key required.

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-decoder-offline-bc0eb748 -d '<json body>'
```

Example prompt: Can you decode this VIN for me — 1HGBH41JXMN109186 — and tell me the manufacturer, where it was built, the model year, and whether the check digit is valid?

## When to prefer this

Use this endpoint when you need a fast, keyless, pay-per-call VIN decode against official NHTSA data without account setup. Ideal for one-off lookups, agent workflows needing manufacturer/origin/year validation, or when you want deterministic offline-style decoding without a subscription. Prefer the sibling 'consolidated vehicle report' endpoint if you also need recall data or emissions info in a single call.

## Known failure modes

- Invalid or malformed VIN (not 17 characters) — returns validation error
- VIN with unsupported or unknown WMI not in NHTSA vPIC tables — partial or empty decode
- Check digit mismatch — flagged in response but not necessarily a hard failure
- Network or payment failure via x402 — call not completed, no charge

## How this service works

The checks your agent runs before it acts: verify a bank account, a phone number, a law in force, the weather or a vehicle — computed from official sources, with provenance in every response. You only pay for answers.

## Output

Returns decoded vehicle attributes derived from the 17-character VIN: the World Manufacturer Identifier (WMI), country and region of assembly, model year, check digit validity status, and any additional deterministic attributes sourced from the official NHTSA vPIC tables.
