## 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 deutscher-wetterdienst-weather-warnings-by-coordinate-44bb15b8 -d '<json body>'
```

Example prompt: Are there any active Deutscher Wetterdienst weather warnings right now for coordinates 52.52°N, 13.41°E? Give me the severity, urgency, and when each warning expires.

## When to prefer this

Choose this endpoint when you specifically need official Deutscher Wetterdienst (DWD) warnings for a German location, with structured severity/urgency/certainty metadata and bilingual text. It is ideal for safety-critical workflows, compliance with German regulatory weather alerts, or when you need precise onset/expires windows rather than generic forecast summaries. Prefer this over general weather APIs when official governmental alert authority and bilingual output are required.

## Known failure modes

- Coordinates outside Germany may return no warnings or an error if DWD has no warn cell coverage
- Invalid lat/lon values outside -90/90 or -180/180 ranges will fail schema validation
- No warnings returned when the area is currently clear — caller must distinguish empty list from error
- DWD upstream data delays may cause stale warning states
- Network timeouts if DWD backend is slow

## How this service works

The warnings the Deutscher Wetterdienst has actually issued for the warn cell containing the coordinate, in German and English, with severity, urgency, certainty and an explicit effective/onset/expires window plus whether the warning is active right now.

## Output

A list of weather warnings issued by the Deutscher Wetterdienst for the warn cell containing the supplied coordinate. Each warning includes the warning text in both German and English, severity level, urgency, certainty, onset/effective/expires timestamps, and a boolean flag indicating whether the warning is currently active.
