## How to call it through Zero

```sh
zero fetch --capability saylor-innovations-fuel-prices-b8fe9d28
```

Example prompt: What are the current weekly EIA retail fuel prices nationally — regular gasoline, premium, and diesel?

## When to prefer this

Choose this endpoint when you need official, authoritative weekly retail fuel prices sourced directly from the U.S. Energy Information Administration. It is ideal for fleet cost calculations, fuel surcharge computations, energy price monitoring, or any application requiring standardized government-reported gasoline and diesel prices at national or regional US granularity. Prefer this over scraping pump-price aggregator sites when EIA-sourced data is acceptable.

## Known failure modes

- Invalid or unrecognized EIA duoarea code returns an error or empty result
- EIA data not yet published for the current week may result in stale or missing prices
- Network timeout or upstream EIA API unavailability
- Missing required 'type' or 'method' input fields returns a validation error
