## 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 agentrxi-us-gasoline-diesel-price-feed-6f9ce14c
```

Example prompt: What's the current average price for regular gasoline across the US this week, and how do cities like Los Angeles, Chicago, and Houston compare — and which regions saw the biggest weekly change?

## When to prefer this

Choose this endpoint when you need structured, ranked US retail fuel price data at national, regional (PADD), state, or metro level with weekly change context — particularly for fleet cost analysis, consumer price monitoring, travel planning, or energy economics research. It covers both gasoline grades and diesel in a single call. Prefer it over scraping EIA directly for agent-ready structured output at very low cost per call.

## Known failure modes

- Invalid grade parameter value (not one of: regular, midgrade, premium, diesel) may return an error or default to regular
- Data may lag by a few days if EIA has not yet published the current week's prices
- Network or upstream EIA data outage may cause service unavailability
- Payment failure (insufficient USDC balance) blocks the request under x402 protocol
