## 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 multi-day-forecast-from-norwegian-meteorological-institute-58656fe6 -d '<json body>'
```

Example prompt: Can you pull the official Norwegian Meteorological Institute 7-day forecast for coordinates 59.9139° N, 10.7522° E — I need daily high and low temps, precipitation, and wind for each day?

## When to prefer this

Choose this endpoint when you need an authoritative, citable weather forecast from a national meteorological service rather than a commercial aggregator, especially when source attribution and official model provenance matter. Ideal for planning decisions that require credible sourcing (e.g. reports, agriculture, construction, research), for any global coordinate without needing a city name, and when you need up to 9 days of structured daily data including min/max temps, precipitation, wind, and weather symbols.

## Known failure modes

- Missing required lat or lon parameters returns a validation error
- Latitude out of range (-90 to 90) or longitude out of range (-180 to 180) causes a bad request error
- Requesting more than 9 days may return partial data or an error
- The last day in the response may be flagged as partial/incomplete
- Upstream MET Norway API downtime may cause a service unavailable response
- Network timeout from the Cloudflare Worker proxy layer

## How this service works

60 paid endpoints with no metering, no API key and no account. Each endpoint has one flat price per call, whatever the size of the request: LLM completions with automatic failover across several large models, read-only EVM tooling over Base, Ethereum, Polygon, Arbitrum and Optimism, and pure crypto utilities that touch no network.

## Output

A JSON object containing the requested coordinates, an array of daily forecast objects (each with min/max temperature, total precipitation, strongest wind speed, and a midday weather symbol), declared units, model run timestamp, data source attribution, license, and the altitude in metres for the queried point.
