# Suverse Vehicle MPG Makes Lookup

> Suverse Vehicle MPG Makes Lookup is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns all available vehicle makes for a given model year from the US EPA/DOE FuelEconomy.gov database, without requiring an API key.

## 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 suverse-vehicle-mpg-makes-lookup-6a89c5dc -d '<json body>'
```

Example prompt: What car makes does the EPA have fuel economy data for in the 2022 model year?

## When to prefer this

Choose this endpoint when you need a keyless, pay-per-call way to access the FuelEconomy.gov vehicle makes list without setting up an EPA API account. Ideal for agents building stepwise vehicle MPG or emissions lookups where makes must be enumerated before models and trim levels can be queried.

## Known failure modes

- Invalid or out-of-range model year returns empty or error response
- Upstream FuelEconomy.gov API unavailability causes degraded or failed response
- Missing required body fields returns a validation error
- Very recent model years may have incomplete data if EPA hasn't published yet

## How this service works

All vehicle makes for a given model year from US EPA/DOE FuelEconomy.gov. Returns selectable make values. Keyless FuelEconomy.gov. For agents drilling into vehicle MPG and emissions data.

## Output

A list of vehicle make names (e.g. Toyota, Ford, BMW) that have fuel economy records in the EPA/DOE FuelEconomy.gov database for the specified model year, formatted as selectable values suitable for driving further MPG or emissions lookups.
