## 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 xynaptic-solar-forecast-af73ce77
```

Example prompt: Can you pull the 48-hour solar production forecast for France? I want to see radiation levels, cloud cover, peak hours, and the estimated output index.

## When to prefer this

Choose this endpoint when you need a forward-looking 48-hour solar energy production forecast specifically for European regions, including structured metrics like radiation, cloud cover, peak hours, and output index. Prefer this over generic weather APIs when the downstream use case is solar energy planning, renewable grid management, or energy trading, and when you need the output index metric specifically. It requires no API key, making it easy to integrate.

## Known failure modes

- Invalid or unsupported region code returns an error
- Coordinates outside European coverage area may return no data
- Service unavailability returns a 402 or 5xx error
- Missing required query parameter causes a 400 bad request
- Stale upstream weather data may reduce forecast accuracy

## How this service works

Xynaptic Solar Forecast — 48h solar production forecast for a European region (radiation, cloud cover, peak hours, estimated output index). Parameter: ?region=fr (or lat/lon). No API key needed, real-time data.

## Output

A 48-hour solar energy production forecast containing solar radiation values, cloud cover percentage, identified peak solar hours, and an estimated output index for the requested European region (specified by region code like 'fr' or by lat/lon coordinates).
