## 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-20ad49ea
```

Example prompt: Are there any active NWS weather watches or warnings right now for coordinates 35.4676° N, 97.5164° W near Oklahoma City?

## When to prefer this

Use this endpoint when you need real-time, official NWS active alert data (watches, warnings, advisories) keyed to a specific US geographic coordinate. Prefer this over general weather forecast endpoints when the user's need is specifically about hazardous conditions, emergency preparedness, or safety-critical decisions rather than routine forecasts.

## Known failure modes

- Non-US coordinates return no results or an error since NWS only covers US territory
- Coordinates in areas with no active alerts return an empty alerts list
- Malformed or out-of-range latitude/longitude values result in a validation error
- Transient NWS API outages may cause upstream fetch failures

## How this service works

## Output
