## 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 macaroon-network-us-weather-forecast-alerts-8e3c6554 -d '<json body>'
```

Example prompt: What's the multi-day weather forecast and any active NWS alerts for latitude 40.7128, longitude -74.0060 right now?

## When to prefer this

Use this endpoint when you need live NWS-sourced weather forecasts and active alert data for a specific US point coordinate. It is the best choice when you need authoritative government weather data (not a third-party estimate), require both forecast and alert information in a single call, and the location is within the United States or its territories. Prefer this over general weather APIs when official NWS alert accuracy is important (e.g. safety-critical applications, emergency routing, outdoor events).

## Known failure modes

- Coordinates outside US territory, territories, or adjacent marine zones return no data (NWS has no global coverage)
- Invalid or malformed latitude/longitude values cause a request error
- NWS API upstream outage may cause timeouts or empty responses
- Coordinates in US waters far from land may return limited or no forecast data
- Missing required 'input' body fields returns a schema validation error

## How this service works

Live multi-day forecast and currently active weather alerts (severe thunderstorm, flood, winter storm, etc.) for a single latitude/longitude point, from the U.S. National Weather Service's own public API (api.weather.gov). Coverage is limited to the United States, its territories, and adjacent coastal/marine zones -- api.weather.gov has no data for points outside that area.

## Output

Returns the NWS multi-day forecast broken into forecast periods (day/night with temperatures, conditions, wind) and a list of currently active weather alerts (e.g. severe thunderstorm warning, flood watch, winter storm advisory) for the given lat/lon point, including alert titles, descriptions, and severity levels.
