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 vextorium-active-tropical-cyclones-nhc-027555eb -d '<json body>'
```

Example prompt: Are there any active hurricanes or tropical storms right now in the Atlantic or Pacific? Give me their names, current wind speeds, positions, and links to the official NHC advisories.

## When to prefer this

Choose this endpoint when you need authoritative, real-time tropical cyclone data sourced directly from the US National Hurricane Center for the Atlantic and eastern/central Pacific basins. Prefer it over generic weather APIs when you specifically need official NHC advisory links, storm track URLs, cyclone typing, or precise storm position and movement data for active named systems.

## Known failure modes

- No active cyclones during off-season results in an empty cyclones array with activos=0
- NHC data feed temporarily unavailable may return a service error
- Request body schema mismatch may return a 400 or validation error
- Network timeout if the upstream NHC source is slow to respond

## How this service works

Active tropical cyclones in the Atlantic and eastern/central Pacific from the US National Hurricane Center: name, type (hurricane, storm...), max wind, pressure, position, movement and links to the official advisory and track.

## Output

Returns a JSON object with the count of active cyclones and an array of cyclone records. Each record includes: storm ID, name, type (e.g. hurricane, tropical storm), latitude, longitude, maximum wind speed in both knots and km/h, pressure in millibars, movement description, last updated timestamp, and URLs to the official NHC advisory and track forecast. Also includes a source attribution and any relevant notes.
