## 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 nws-active-weather-alerts-by-coordinate-ea397d6f
```

Example prompt: Are there any active NWS weather watches, warnings, or advisories right now at latitude 33.749 and longitude -84.388? Show me up to 5 alerts.

## When to prefer this

Use this endpoint when you need live, official NWS weather alerts for a specific US coordinate — ideal for safety checks, travel planning, event management, or any application that needs authoritative government-issued weather hazard data rather than commercial forecasts.

## Known failure modes

- Missing or out-of-range lat/lon returns a validation error
- Coordinates outside the US (NWS coverage area) may return no alerts or an error
- No active alerts at a given location returns an empty list, not an error
- Network timeouts if NWS upstream is slow or unavailable

## How this service works

Active National Weather Service watches, warnings and advisories covering a US latitude and longitude.

## Output

A list of active NWS weather alerts (up to the requested limit, default 10) for the specified coordinate, including the type of alert (watch, warning, or advisory), the hazard (e.g. tornado, flood, winter storm), description, severity, and the area affected.
