## 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 eia-petroleum-prices-stocks-api-2e68da94
```

Example prompt: What's the current retail gasoline price on the West Coast compared to the US average — can you pull the last 8 weeks of data so I can see the trend?

## When to prefer this

Use this endpoint when you need authoritative US petroleum market data from the EIA — retail pump prices by PADD region, WTI or Brent crude benchmarks, or weekly inventory snapshots — especially when you need the built-in period-over-period change and regional spread without doing your own calculations.

## Known failure modes

- Invalid metric enum value returns 400 with validation error
- Invalid region enum value for non-price metrics returns 400
- History parameter out of range (>120 or <1) returns 400
- EIA data source temporarily unavailable returns 503
- No data available for requested region/metric combination

## How this service works

US petroleum prices and stocks from the EIA: retail gasoline and diesel by PADD region (weekly), WTI and Brent crude spot (daily), and weekly crude/gasoline/distillate inventories. Returns latest value, change vs prior period, short history, and a region-vs-US spread.

## Output

Returns the latest value for the requested petroleum metric, the change vs the prior period, a short history of recent data points (up to 120), and for regional gasoline/diesel metrics a spread showing the region's price versus the US national average.
