## 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 opendata402-hourly-weather-forecast-6285ab14
```

Example prompt: What's the hour-by-hour weather forecast for the next 48 hours at latitude 59.91 and longitude 10.75 — include temperature, wind speed, and whether it will rain?

## When to prefer this

Choose this endpoint when you need precise, point-specific hourly weather forecasts anywhere on Earth — including remote locations without a named city. It is ideal for logistics, outdoor events, construction, agriculture, drone operations, and travel planning where granular hourly data (temperature, wind, precipitation, humidity, pressure) over the next 48 hours matters. Prefer it over general weather APIs when global coverage and official meteorological model data from MET Norway is required.

## Known failure modes

- Missing lat or lon query parameters returns a 400-level error
- Coordinates outside valid range (lat: -90 to 90, lon: -180 to 180) may return an error or no data
- Payment not completed or insufficient USDC balance returns a 402 Payment Required response
- MET Norway model temporarily unavailable results in a 503 or timeout
- Malformed coordinate strings that don't match the expected numeric pattern are rejected

## How this service works

Weather forecast for any point on Earth for the next 48 hours, hour by hour: temperature, wind speed and direction, precipitation, cloud cover, humidity, pressure and a weather symbol. Model run by the Norwegian Meteorological Institute (MET Norway), updated several times a day. Use it for travel, logistics, events and outdoor work anywhere.

## Output

A 48-hour hour-by-hour weather forecast for the given lat/lon coordinates, including temperature (°C), wind speed (m/s), wind direction (degrees), precipitation amount (mm), cloud cover (%), relative humidity (%), atmospheric pressure (hPa), and a symbolic weather condition indicator. Data is sourced from MET Norway numerical weather prediction models updated several times daily.
