## 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 quant-agent-shop-weather-forecast-e73c7051 -d '<json body>'
```

Example prompt: What's the weather forecast for Rome over the next 5 days — give me the daily highs and lows, rain chances, and an hourly breakdown for the first 24 hours.

## When to prefer this

Choose this endpoint when you need fast, current or near-future weather data (up to 7 days) for any global coordinate or city, especially for travel, logistics, or event planning contexts. Prefer over generic weather APIs when MET Norway data quality and sub-second latency matter. Not suitable for historical weather queries or official severe-weather warnings.

## Known failure modes

- Invalid or out-of-range latitude/longitude returns an error
- Neither city nor lat/lon provided results in a validation error
- Unknown or misspelled city name may return a not-found error
- Upstream MET Norway outage may cause a service-unavailable response
- Requesting more than 7 days or more than 48 hours returns a validation error

## How this service works

Weather forecast for coordinates or a city name: current temperature, humidity, wind, cloud, pressure and conditions, an hourly forecast up to 48 hours, and daily highs, lows and rain up to 7 days. Data from MET Norway. Use for travel, event or logistics planning. Not for past weather or official warnings. Times in UTC. Typical response under 1 s. Failed calls are not charged.

## Output

A JSON object containing: current conditions (temperature, humidity, wind speed and direction, cloud cover, pressure, weather description), an hourly array for up to 48 hours, and a daily array for up to 7 days with high, low, and rain probability. All times are in UTC.
