## 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-us-fuel-prices-aed5f36c -d '<json body>'
```

Example prompt: What are the current US national average fuel prices for all fuel types — regular, premium, diesel, E85, and electricity — from the official EPA/DOE source?

## When to prefer this

Use this endpoint when you need official, authoritative US national-average fuel prices from a government source (EPA/DOE) without requiring any API key. Prefer this over scraping third-party price aggregators when data credibility matters, or when estimating fuel costs for budgeting, fleet management, route planning, or vehicle cost comparisons.

## Known failure modes

- Upstream FuelEconomy.gov API unavailability returns a proxy error
- Payment failure (x402) if USDC balance is insufficient
- Empty or null values if FuelEconomy.gov has not updated prices recently
- Network timeout if the upstream government endpoint is slow to respond

## How this service works

## Output
