## 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 eu-power-grid-events-feed-dunkelflaute-storm-negative-prices-records-b221b766 -d '<json body>'
```

Example prompt: Pull the latest EU power grid event feed and tell me if there are any active Dunkelflaute, storm, negative price episodes, or grid records happening right now in the German electricity market.

## When to prefer this

Choose this endpoint when you need a curated event-driven signal — not raw time-series data — specifically for Dunkelflaute, storm, negative price, or record-breaking grid conditions in Germany and the EU. It is ideal for alert-driven agents, trading bots, and flexible-load controllers that need to react to discrete grid anomalies rather than poll continuous price streams.

## Known failure modes

- 402 Payment Required if x402 micropayment header is missing or invalid
- Empty event list if no significant events are currently active
- Stale data if upstream ENTSO-E or SMARD feed is delayed
- Network timeout if the halowerk.com service is temporarily unavailable
- Malformed request body causing 400 Bad Request
