# Delx WMI Decode

> Delx WMI Decode is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Decodes a 3-character World Manufacturer Identifier (WMI) using the NHTSA vPIC database to return manufacturer name and vehicle type.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/wmi-decode
- Price: $0.003/call
- Payment: x402
- Status: unknown

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 delx-wmi-decode-59fd26eb -d '<json body>'
```

Example prompt: Can you decode the WMI '1FT' and tell me which manufacturer it belongs to and what type of vehicle it represents?

## When to prefer this

Use this endpoint when you have a WMI or the first 3 characters of a VIN and need to quickly resolve the manufacturer name and vehicle type without building your own NHTSA integration. It is ideal for VIN enrichment pipelines, automotive data validation, and fraud detection workflows where per-lookup micropayment pricing via x402 is acceptable.

## Known failure modes

- Invalid or unrecognized WMI returns no match or an error
- WMI shorter or longer than 3 characters may be rejected
- NHTSA vPIC database may not contain newly issued or obscure WMIs
- Payment failure or insufficient USDC balance blocks the call

## How this service works

Decode a 3-char WMI via NHTSA vPIC for $0.003 USDC into manufacturer and vehicle type. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

## Output

Returns the manufacturer name (e.g. 'Ford Motor Company') and vehicle type (e.g. 'Passenger Car', 'Multipurpose Passenger Vehicle') associated with the given 3-character WMI code, sourced from the NHTSA vPIC database.
