## 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 vextorium-world-weather-forecast-af49410a -d '<json body>'
```

Example prompt: Can you get me the current weather conditions and a 5-day forecast for Madrid (latitude 40.42, longitude -3.7)? I need temperature, rain, wind, and sky state.

## When to prefer this

Choose this endpoint when you need authoritative, globally-covering weather data sourced from MET Norway for any coordinates on Earth — especially when you need both current conditions and a multi-day daily forecast (up to 9 days) in a single call, including wind, precipitation, cloud cover, humidity, and pressure. Prefer this over generic weather APIs when MET Norway's open data license (CC BY 4.0) is acceptable and you want structured daily forecasts by lat/lon without requiring a city name or address.

## Known failure modes

- Missing lat or lon fields returns a validation error
- lat/lon values outside valid geographic ranges may return errors or empty results
- dias values outside 1–9 range may default to 3 or return an error
- MET Norway upstream unavailability could cause timeouts or empty responses
- Payment failure (x402) prevents the call from completing

## How this service works
