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-alerts-national-11d1939e -d '<json body>'

Example prompt: Can you pull up all the active National Weather Service alerts happening right now across the entire US and let me know what types of warnings are out there?

## When to prefer this

Use this endpoint when you need a single, no-parameter call to get a complete snapshot of all active NWS weather alerts across the entire US. Prefer it over weather forecast APIs when the goal is emergency/alert monitoring rather than temperature or precipitation data. Ideal for alert dashboards, safety bots, or routing logic that reacts to severe weather events nationwide.

## Known failure modes

- NWS upstream API unavailable — returns 5xx error or empty body
- No active alerts at query time — returns empty alerts array
- Rate limiting or payment failure — returns 402 or 429 status
- Stale data if NWS feed has not been refreshed recently
