# Vehicle VIN Toolkit – Models by Make and Year

> Vehicle VIN Toolkit – Models by Make and Year 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).

Lists all vehicle models NHTSA has on record for a specific make and model year, with optional filtering by vehicle type or model name.

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-models-by-make-and-year-b0b12318
```

Example prompt: What car models does NHTSA have on record for Honda in the 2018 model year? Show me up to 50 results filtered to cars only.

## When to prefer this

Use this endpoint when you need to enumerate the official NHTSA-recorded models for a specific make and model year, especially when building vehicle catalogs, validating inventory, or populating dropdowns for VIN-related workflows. Prefer this over generic web search when you need structured, authoritative NHTSA data with model IDs suitable for downstream VIN decoding or lookup calls.

## Known failure modes

- Make not recognized by NHTSA — returns empty model list or error
- Invalid or out-of-range model year — returns validation error
- Vehicle type value not in allowed enum — returns bad request error
- Limit out of range (below 1 or above 100) — returns validation error
- NHTSA vPIC API unavailable — response may be degraded or empty with degraded flag set to true
- Network timeout from upstream NHTSA service

## How this service works

List the vehicle models NHTSA records for a make in a given model year, optionally filtered by vehicle type.

## Output

Returns a structured object containing the make name, model year, a list of model objects (each with model name, model ID, make, and vehicle type), the total number of models found, the number matching any filter, the NHTSA source URL, and a timestamp. Also includes summary and verdict fields, and a degraded flag if the data source was partially unavailable.
