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-us-state-area-d06b31ce -d '<json body>'
```

Example prompt: Are there any active National Weather Service alerts for New York state right now? I need the live feed for ops planning.

## When to prefer this

Use this endpoint when you need real-time, official US National Weather Service alerts for a specific state or area — especially for operations, logistics, supply chain, or field safety decisions. Prefer this over general weather APIs when alert status (warnings, watches, advisories) matters more than forecast data.

## Known failure modes

- Invalid or unrecognized area code returns empty results or error
- NWS upstream API downtime causes failed or stale response
- No active alerts for the area returns an empty array
- Malformed query parameter (e.g. lowercase or full state name instead of code) may return no results
