## 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 forgemesh-tornado-warning-watch-feed-f675428b -d '<json body>'
```

Example prompt: Pull the current tornado warning and watch feed right now — I need all active US tornado alerts with their affected zones, severity, and urgency so I can decide whether to halt our delivery operations.

## When to prefer this

Choose this endpoint when you need a continuously refreshed, normalized JSON snapshot of all active US tornado warnings and watches without parsing raw NWS CAP/ATOM feeds yourself. Ideal for safety-notification bots, logistics-halt triggers, or emergency dashboards that need sub-2-minute latency on tornado activity nationwide. Prefer over weather APIs that bundle tornado data inside broader severe-weather feeds when you specifically need tornado-only signal with structured zone and severity metadata.

## Known failure modes

- No active alerts: returns empty list or zero-record response when no tornadoes are currently warned or watched
- Upstream NWS feed delay: data may lag up to 2 minutes behind NWS issuance
- Payment failure: 402 response if USDC payment is not attached or insufficient
- Service unavailable: 5xx if forgemesh ingest pipeline is down
- Malformed body: 400 if POST body structure does not match expected schema

## How this service works

Nationwide tornado warning and watch feed: every currently active US tornado warning or tornado watch — affected zones, severity, urgency, and full alert text — as normalized JSON, refreshed every 2 minutes. Built for safety-notification and logistics-halt agents that need the fastest possible signal on tornado activity.

## Output

A normalized JSON object listing every currently active US tornado warning and tornado watch, including the affected geographic zones, severity classification, urgency level, and full NWS alert text. Data is refreshed every 2 minutes so callers get near-real-time situational awareness.
