Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-forgemesh-io-tornado-watch-warning-tracker-87da145f -d '<json body>'
```

Example prompt: Pull up all currently active tornado warnings and watches anywhere in the US right now — I need the affected zones, severity, urgency, and the official alert text for each one.

## When to prefer this

Use this endpoint when you need a real-time, nationwide view of all active tornado threats at once — ideal for safety alerting systems, fleet/logistics halt automation, news monitoring agents, or emergency response tools that need official NWS tornado alert data without filtering by a specific location. Prefer this over point-based weather APIs when you need the full US picture rather than conditions at a single coordinate.

## Known failure modes

- Empty result set returned when no tornado activity is currently active (not a failure — expected behavior)
- HTTP 402 Payment Required if USDC micropayment is not included or fails
- Stale data risk if called within the 2-minute refresh window between updates
- Malformed request body may result in 400 Bad Request

## How this service works

Live nationwide feed of active tornado warnings and watches from the official US alerting authority — zones affected, severity, urgency, and alert text for each. Use for real-time safety alerting, fleet/delivery-halt automation, and news agents tracking severe weather. Updated every 2 minutes; empty results mean no tornado activity, not a failure.

## Output

A list of all currently active tornado warnings and tornado watches across the United States, each with affected geographic zones, severity classification, urgency level, and the full official alert text from the National Weather Service. An empty result indicates no current tornado activity, not an error.
