## 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 gridhub-live-electricity-market-data-c74e11a0
```

Example prompt: What's the current wholesale electricity price and demand for the GB grid right now?

## When to prefer this

Choose this endpoint when you need the most recent single snapshot of wholesale electricity price and demand for a specific grid zone in real time. Prefer this over the historical endpoint when you only need the current value, not a time series. It covers 25 major grids across the US, UK, Australia, and Europe, making it ideal for live market monitoring, cost optimization triggers, or energy intelligence dashboards.

## Known failure modes

- Invalid zone ID returns an error — must use one of the 25 supported enum values (e.g. US-CAISO, GB, AU-NSW)
- Data may be delayed if the upstream grid operator has not published a new interval yet
- Payment failure (402) if USDC payment is not provided or insufficient — use ?sample=true for a free truncated response
- Network timeout if the grid operator's data feed is temporarily unavailable

## How this service works

Live wholesale electricity prices, demand, and generation mix across 25 grids in the US, UK, Australia, and Europe. Pay-per-call API access from $0.001.

## Output

A JSON object containing the zone identifier, license, attribution, and a metrics block with the latest wholesale price (value, unit like GBP/MWh or USD/MWh, timestamp, and resolution) and demand (value in MW, timestamp, and resolution). Generation mix data is included where published by the grid operator.
