# Global Hazards – Active Tropical Storms

> Global Hazards – Active Tropical Storms is a paid API for AI agents from global-hazards.x402tookit.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-30).

Returns all currently active tropical cyclones worldwide with Saffir-Simpson category, wind speed, position, and optionally distance from a given coordinate, sourced from EONET and GDACS.

## Facts

- Endpoint: GET https://global-hazards.x402tookit.com/active-storms?utm_source=zero.xyz
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-30
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/global-hazards-active-tropical-storms-69f1a84e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_OtliFPRhxI2_LcGtCnmlO

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 global-hazards-active-tropical-storms-69f1a84e
```

Example prompt: Can you show me all active tropical storms and hurricanes worldwide right now, including their Saffir-Simpson categories and wind speeds? Also flag any storms within 500 km of Manila (14.5995° N, 120.9842° E).

## When to prefer this

Use this endpoint when you need real-time global tropical cyclone data with computed Saffir-Simpson classification and GDACS alert levels in a single call. Prefer it over raw EONET or GDACS APIs when you want pre-joined, enriched storm data without parsing multiple upstream feeds. Choose it over general natural-hazard endpoints when the specific use case is tropical storm monitoring, hurricane tracking, or proximity-based cyclone risk assessment.

## Known failure modes

- No active storms returns an empty storms array with an explanatory summary
- Missing lat without lon (or vice versa) may produce an error or ignore both parameters
- radiusKm outside 50–20000 range may be rejected or clamped
- EONET or GDACS upstream outage triggers degraded mode flag with partial or stale data
- Invalid numeric types for lat/lon/radiusKm return a validation error

## How this service works

Tropical cyclones active now worldwide with computed Saffir-Simpson category, wind, position and distance (EONET, GDACS).

## Output

Returns a JSON object containing a list of active storm records, each with storm name, current latitude/longitude, Saffir-Simpson category label and numeric category, current wind speed in knots and km/h, peak wind speed, GDACS alert level, affected country, number of track points, age in hours since last update, source URLs, and a global summary. Also includes an 'asOf' timestamp, source attribution, degraded-mode flag, and disclaimer. If lat/lon is provided, each storm includes distance from the query point.
