## 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-7e29cd2f
```

Example prompt: What's the latest retail gasoline price on the West Coast, including the last 8 weeks of history and how it compares to the national average?

## When to prefer this

Use this endpoint when you need official US government EIA petroleum data — retail pump prices, crude oil benchmarks, or inventory stocks — with built-in regional breakdowns, period-over-period change, and short historical series in a single call. Prefer over scraping EIA directly or using financial data APIs when you need structured, agent-ready JSON with PADD region spreads included.

## Known failure modes

- Invalid metric enum value returns 422 unprocessable entity
- Invalid region enum value returns 422 unprocessable entity
- History value outside 1-120 range returns 422 validation error
- EIA source data temporarily unavailable may return 503 or stale data
- Payment not provided or insufficient returns 402 Payment Required

## 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 versus the prior period, a short history array of recent data points (up to 120), and for regional metrics a spread versus the US average. Covers retail gas and diesel by PADD region (weekly), WTI and Brent crude spot prices (daily), and crude/gasoline/distillate inventory stocks (weekly).
