## 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 hawaii-conditions-trail-conditions-by-island-d98f8d8b
```

Example prompt: What are the current trail conditions on Maui — are any trails closed or flagged with safety alerts right now?

## When to prefer this

Choose this endpoint when you need real-time, government-sourced trail status and safety alerts specifically for Hawaiian islands. It is ideal for travel planning agents, outdoor activity assistants, or safety-check workflows where up-to-date NPS and USGS data matters more than crowd-sourced reviews. Prefer this over generic hiking databases when the user is specifically asking about Hawaii.

## Known failure modes

- Invalid or unsupported island name returns an error or empty result
- Upstream NOAA/NPS data unavailable causes stale or missing conditions
- Trail-level granularity may vary by island — some islands may return aggregate rather than per-trail data
- Network timeout from Vercel serverless function under heavy load

## How this service works

Real-time surf, weather, trails, volcano, ocean safety, and restaurant data for every Hawaiian island. Built for AI agents. Powered by NOAA, USGS, NPS, Open-Meteo and Google Places.

## Output

Returns a JSON object with the trail name, open/closed status, difficulty rating, length in miles, a narrative conditions description, any active safety alerts as an array of strings, and a timestamp of when the data was last updated — all sourced in real time from NPS and related government data providers.
