## 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 storm-station-247-us-weather-forecast-alerts-api-e705e13e
```

Example prompt: What's the full weather forecast for Chicago, IL right now — give me the next 48 hours hour by hour, the 10-day outlook, and any active storm warnings or alerts in the area.

## When to prefer this

Choose this endpoint when you need real-time US weather forecasts with comprehensive active NWS alert coverage in a single call, especially when you need both the short-term hourly detail (48 hours) and medium-term daily outlook (10 days) together. It is well-suited for agents that must surface safety-critical weather warnings. Prefer it over generic weather APIs when NWS alert text completeness and instrument-ranked data quality matter.

## Known failure modes

- Missing or invalid 'at' query parameter returns an error — location must be a recognizable US place name or coordinate
- Non-US locations may not be supported or may return no data
- Payment failure (HTTP 402) if USDC micropayment is not properly handled by the x402 protocol
- Ambiguous location strings may return results for an unintended place
- No active alerts will return an empty alerts array, not an error
