## 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 epa-fueleconomy-gov-vehicle-model-years-lookup-0d36b692 -d '<json body>'
```

Example prompt: What model years are available in the EPA FuelEconomy.gov database? I want to build a vehicle MPG lookup and need to know which years I can query.

## When to prefer this

Choose this endpoint when you need a keyless, micropayment-based proxy to the EPA FuelEconomy.gov years list without managing your own API credentials or rate limits. Ideal for agents building vehicle fuel economy or emissions tools that need a dynamic, up-to-date list of valid model years as a first step before querying MPG or emissions data.

## Known failure modes

- Upstream FuelEconomy.gov API unavailable — proxy may return 5xx or timeout
- Malformed request body may return 400 validation error
- Payment failure (x402) if USDC micropayment is not processed correctly
- Empty or unexpected response if FuelEconomy.gov data is temporarily inconsistent
