## 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 forgemesh-car-mpg-lookup-acdb335e -d '<json body>'
```

Example prompt: What's the official EPA city, highway, and combined MPG for a 2019 Honda Accord — show me all the engine and transmission variants available.

## When to prefer this

Use this endpoint when you need official EPA fuel economy figures (city/highway/combined MPG), fuel type, or CO2 emissions data for any US-market vehicle from 1984 onward. It supports both VIN-based lookup (for exact vehicle identification) and year/make/model queries, and returns all engine/transmission variants with IDs for precise filtering. Prefer this over generic car data APIs when EPA test-cycle accuracy and CO2 data are required.

## Known failure modes

- Vehicle not found for given make/model/year combination — no results returned
- Invalid or malformed VIN — decoding fails or returns error
- Model year before 1984 — outside supported range
- Ambiguous model name matching multiple makes — requires more specific input
- Invalid vehicle_id provided — returns error or empty result

## How this service works

MPG lookup for any US-market car since 1984: official test-cycle city, highway, and combined miles per gallon plus fuel type and CO2 per mile, by year/make/model or VIN. Multiple engine/transmission variants are returned with ids so you can query the exact one. Clean structured JSON.

## Output

A structured JSON response listing all engine/transmission variants for the queried vehicle, each with a unique vehicle_id and official EPA test-cycle city MPG, highway MPG, combined MPG, fuel type, and CO2 emissions per mile. Multiple variants allow precise selection of the exact configuration.
