## 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-natural-gas-data-henry-hub-price-storage-8b45c4ca
```

Example prompt: What's the current Henry Hub natural gas spot price from the EIA, and can you also pull the last 10 daily readings so I can see the recent trend?

## When to prefer this

Use this endpoint when you need authoritative US natural gas market data sourced directly from the EIA — specifically Henry Hub spot prices or weekly underground storage figures with regional breakdowns. Prefer this over generic financial data APIs when you need EIA-sourced storage (Bcf) data with week-over-week change calculations, or when you need regional storage breakdowns (East, Midwest, South Central, Mountain, Pacific). Best suited for energy market monitoring, commodity analysis, or any workflow requiring official government energy statistics.

## Known failure modes

- Invalid metric enum value returns 400 error
- Invalid region enum value returns 400 error
- History parameter outside 1–120 range returns validation error
- EIA upstream data unavailable may cause delayed or stale data response
- Missing required 'type' or 'method' fields in input object returns 400

## How this service works

US natural gas data from the EIA: Henry Hub spot price (daily) and weekly working gas in underground storage (Bcf, Lower 48 or region). Returns latest value, change vs the prior period (week-over-week for storage), and short history. Source: U.S. Energy Information Administration.

## Output

Returns the latest value for the requested metric (Henry Hub spot price in USD/MMBtu or working gas storage in Bcf), the change vs. the prior period (daily for Henry Hub, week-over-week for storage), and an optional array of recent historical data points. For storage, the region (e.g. lower_48, midwest) is reflected in the response.
