## How to call it through Zero

```sh
zero fetch --capability gridhub-live-electricity-market-brief-15ef57d5
```

Example prompt: What's the current wholesale electricity price in Great Britain right now, and is it high or low compared to normal?

## When to prefer this

Choose this endpoint when you need a fast, human-readable snapshot of current electricity market conditions for a specific grid zone — especially when you want the price in context (percentile ranking + plain-language summary) rather than raw numbers. Prefer this over the full snapshot endpoint when brevity matters, and over the historical endpoint when only real-time conditions are needed. Ideal for decision-making triggers (e.g. load shifting, cost alerts) and dashboard summaries.

## Known failure modes

- Invalid zone identifier returns a 400/422 error — only the 25 supported zone enum values are accepted
- Upstream grid data unavailability may return a 503 or stale/null values for some metrics
- Payment not included or insufficient (x402 protocol) results in a 402 Payment Required response
- Rate limiting or quota exhaustion may return a 429 error

## 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, current wholesale price with unit and percentile ranking, demand status, and a short natural-language summary sentence (e.g. 'Price is high (82nd percentile); demand is normal.') — designed to be directly readable by a human or agent without further processing.
