## 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-dispatch-api-epex-24h-price-forecast-00c42cee -d '<json body>'
```

Example prompt: Pull the EPEX 24-hour price and volatility forecast for the German power market so I can decide when to dispatch my flexible load today.

## When to prefer this

Choose this endpoint when you need a forward-looking 24-hour EPEX price and volatility view for the German/EU power market to inform flexible-load dispatch, battery scheduling, or energy trading decisions. Prefer it over real-time spot endpoints when planning ahead rather than reacting to current prices, and over generic energy data APIs when you need ENTSO-E and SMARD sourced forecasts with volatility context.

## Known failure modes

- 402 Payment Required if x402 payment is not included
- Empty or malformed POST body may result in validation errors
- Stale data if upstream ENTSO-E or SMARD feeds are delayed
- Rate limiting if too many calls are made in quick succession
- Schema mismatch if required nested input fields are missing

## How this service works

Energy-trading and flexible-load agents buy this endpoint to compare the next 24 hours of EPEX prices and volatility.

## Output

A structured response containing the next 24 hours of EPEX spot market prices and associated volatility metrics, drawing on ENTSO-E and SMARD licensed data, enabling agents to compare price windows and make dispatch or trading decisions.
