## 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-hourly-electric-grid-demand-api-1a839f3c
```

Example prompt: Pull the last 72 hours of hourly electricity demand data for the CAISO balancing authority from the EIA grid monitor.

## When to prefer this

Choose this endpoint when you need authoritative, free-at-source US federal electricity grid demand data from EIA-930, especially for major balancing authorities like CAISO, PJM, ERCOT, or NYISO, and want normalized JSON output with caching — ideal for energy analytics, grid monitoring, or demand forecasting pipelines that need reliable hourly MWh figures.

## Known failure modes

- Invalid or unsupported balancing authority code returns an error
- Requested time range exceeds available data coverage
- Missing required 'ba' or 'length' fields returns a validation error
- EIA upstream data gaps may result in incomplete hourly records
- Payment failure via x402 protocol blocks the request

## How this service works

US electricity grid demand (MWh/hour) from EIA. POST body: {ba, length, start?}.

## Output

A normalized JSON response containing hourly electricity demand values in MWh for the specified balancing authority and time window, sourced from EIA-930 federal data and served cached for performance.
