# Vehicle VIN Toolkit – Model Year Code Converter

> Vehicle VIN Toolkit – Model Year Code Converter is a paid API for AI agents from vehicle-vin.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Converts a vehicle model year (1980–2039) to its VIN position-10 character code, or decodes a VIN position-10 code to its one or two possible model years.

## Facts

- Endpoint: GET https://vehicle-vin.x402tookit.com/model-year-code?utm_source=zero.xyz
- Price: $0.02/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 vehicle-vin-toolkit-model-year-code-converter-531e59c9
```

Example prompt: What VIN position-10 code corresponds to model year 2023, and what are the possible years for that code?

## When to prefer this

Use this endpoint when you need to quickly convert between a numeric vehicle model year and its single-character VIN position-10 encoding (or vice versa), without needing a full VIN decode. It is simpler and cheaper than a full VIN decoder when only the model year character is needed.

## Known failure modes

- Year out of supported range (1980–2039) returns error or null result
- Invalid or unrecognized position-10 code character returns null
- Neither year nor code parameter supplied results in a bad request
- Providing both year and code simultaneously may produce undefined behavior

## How this service works

Convert a model year (1980-2039) to its VIN position-10 code, or a code to its two possible years.

## Output

Returns the VIN position-10 code for a given model year, or the one or two model years that a given position-10 code can represent, along with a human-readable summary and disclaimer about the conversion.
