## 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 us-national-weather-service-forecast-by-coordinates-3e40d9e1
```

Example prompt: What's the official National Weather Service forecast for New York City — latitude 40.71, longitude -74.01 — for the next several periods including temperature, wind, and chance of rain?

## When to prefer this

Choose this endpoint when you need authoritative, official US government weather forecast data (not a third-party aggregator) for a specific latitude/longitude within the United States. Ideal when regulatory compliance, data provenance, or trust in official sources is important. Best for point forecasts rather than global or international weather needs.

## Known failure modes

- Coordinates outside the US (lat/lon not within valid US bounds 17–72°N, -180 to -60°W) will return an error or no forecast
- NWS API upstream outage causes downstream failure
- Invalid or missing lat/lon parameters return a validation error
- Coordinates over open ocean with no NWS grid coverage may fail

## How this service works

Use when you need the official National Weather Service forecast for a latitude/longitude inside the United States: next periods with temperature, wind, chance of precipitation and a short summary, plus the nearest city. US government data.

## Output

An ordered list of forecast periods (e.g. Tonight, Thursday, Thursday Night…) each containing: period name, temperature with unit, wind speed and direction, short weather summary/description, precipitation chance, and the nearest city to the queried coordinates. Data sourced directly from NOAA's official NWS API.
