```sh
zero fetch --capability oracle-network-jp-data-fly-dev-ffd5adea
```

Example prompt: Can you check the latest disaster and weather alerts from Japan's Meteorological Agency right now and tell me if there are any active warnings or special advisories?

## When to prefer this

Choose this endpoint when you need authoritative, near-real-time disaster and weather warning data specifically from Japan's official meteorological authority (JMA). Ideal for agents monitoring Japanese natural disaster risk, severe weather, or public safety conditions. Prefer over general weather APIs when official Japanese government sourcing and Atom feed fidelity matter.

## Known failure modes

- JMA upstream feed unavailable — may return empty entries or error
- Stale data if refresh cycle is delayed beyond 10 minutes
- No alerts present returns count: 0 with empty entries array
- Network timeout if fly.dev host is under load
- Payment required (402) if x402 micropayment not included

## How this service works

Real-time Japanese weather and disaster alert feed from JMA (Japan Meteorological Agency) for AI agents requiring Japan-specific official emergency advisories. Includes weather warnings, special warnings, and advisories in Atom feed format. Refreshed every 10 minutes.

## Output

Returns a JSON payload containing an array of JMA alert entries (type: 'jma'), an integer count of current alerts, and a collected_at timestamp. Each entry represents a weather warning, special warning, or advisory as sourced from the JMA Atom feed, refreshed every 10 minutes.
