## 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 skyfeed-us-severe-weather-alerts-1dfd9ddc
```

Example prompt: Are there any active severe weather alerts in California right now — like red flag warnings or fire weather watches?

## When to prefer this

Choose this endpoint when you need real-time US severe weather alert data (NWS-sourced) by state code or coordinates, billed per-call with no API key required — ideal for agents that need on-demand alerts without a subscription. Prefer over general weather APIs when NWS official alert status (Red Flag, Tornado Watch, Hurricane Warning, etc.) with urgency and severity classifications is specifically needed.

## Known failure modes

- Missing both state and lat/lon parameters returns a 400 validation error
- Invalid state code (e.g. non-US territory) may return zero alerts or an error
- lat/lon coordinates outside the US will return no NWS alerts since coverage is US-only
- Payment failure or insufficient USDC balance returns a 402 Payment Required response
- NWS upstream outage may cause empty or error responses

## How this service works

Pay-per-call weather forecasts (global), current conditions, US severe-weather alerts, earthquakes, public holidays and a bundled travel check for AI agents. No API key: pay USDC on Base per call via x402.

## Output

A JSON object containing a count of active alerts and an array of alert objects, each with event type (e.g. Red Flag Warning), affected area, severity level, urgency, onset and end times, issuing NWS office, and a plain-English headline. Source is attributed to the US National Weather Service public domain data.
