## 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 met-norway-hourly-weather-forecast-via-x402-gateway-0c11f084 -d '<json body>'
```

Example prompt: What's the hourly weather forecast for the next 48 hours at latitude 59.9139, longitude 10.7522 — I need temperature, precipitation, and wind?

## When to prefer this

Use this endpoint when you have a specific latitude/longitude and need a structured hourly weather forecast (up to 240 hours ahead) with rich meteorological fields from MET Norway. Prefer this over name-based weather APIs when you already have geocoded coordinates. Do not use for historical weather data, severe weather alerts, or when you only have a place name (geocode first). Best for agentic workflows that pay per call via x402 micropayments.

## Known failure modes

- Coordinates out of range (lat outside -90/90 or lon outside -180/180) — validation error
- Hours parameter outside 1-240 range — validation error
- MET Norway upstream unavailable — 502 or timeout
- Payment not settled via x402 — 402 Payment Required
- Malformed request body missing required latitude/longitude — 400 Bad Request

## How this service works

Use when you need a weather forecast, temperature or precipitation for the next hours or days at a place given by coordinates. Do not use for historical weather, severe weather alerts or places given only by name (geocode first). Returns JSON with the hourly weather forecast for a latitude and longitude: temperature, precipitation, wind, humidity, cloud cover and a weather symbol, from MET Norway for 0.003 USDC per call. Typical response time 1500 ms (p95). Category: Data.

## Output

A JSON object containing: the queried latitude, longitude, altitude (meters), update timestamp, attribution to MET Norway, and an array of hourly entries each with time, temperature (°C), precipitation (mm), precipitation hours, wind speed (m/s), wind direction (degrees), humidity (%), cloud cover (%), pressure (hPa), and a weather symbol code. Also includes a 'next' field suggesting follow-up calls in the same service family.
