## 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 netzhandwerker-negative-electricity-price-forecast-e0cfa2fd -d '<json body>'
```

Example prompt: Can you forecast any negative electricity price windows coming up in the German day-ahead market over the next 24 hours so I can schedule my battery storage to charge during those periods?

## When to prefer this

Use this endpoint when you need to proactively identify and act on upcoming negative electricity price events in European energy markets — particularly for battery charge scheduling, flexible load shifting, algorithmic trading signal generation, or ESG reporting on renewable surplus. Prefer this over generic price lookup endpoints when you specifically need forward-looking negative price predictions rather than current or historical price data.

## Known failure modes

- Unsupported market zone returns 400 or empty result
- Forecast horizon too far in advance returns low-confidence or no data
- Service temporarily unavailable due to upstream grid data outage returns 503
- Invalid or missing required parameters return 422 validation error
- Payment not processed correctly returns 402 payment required

## How this service works

Live electricity prices, carbon intensity, grid load, renewable share, flexibility windows, battery arbitrage, trading signals and ESG reporting for autonomous agents.

## Output

Returns a forecast of upcoming negative electricity price windows including timestamps, predicted price levels, probability scores, and trading signals indicating when and where prices are expected to drop below zero — useful for battery arbitrage scheduling and demand flexibility planning.
