## 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 snowpack-weather-api-70d9ffdf
```

Example prompt: What are the live weather and snow conditions right now at Park City Mountain Resort — including any avalanche danger?

## When to prefer this

Choose this endpoint when you need real-time, resort-specific weather and snow conditions for one of SNOWPACK's sixty-three supported mountains, especially when avalanche danger, ski patrol status, or lidar-mapped run conditions are needed alongside basic weather. Prefer it over generic weather APIs when the query is explicitly ski- or mountain-sport-related and the resort is likely in the supported network.

## Known failure modes

- Resort name not recognized — returns error if the place query does not match one of the sixty-three supported resorts
- Missing required 'place' query parameter — returns a validation error
- Resort temporarily offline or data feed unavailable — may return stale or partial data
- Ambiguous resort name — query matches multiple resorts and requires disambiguation

## How this service works

Lidar-mapped mountains and runs, live weather and snow, avalanche danger, verified ski patrol and SOS, and your skiing measured, at sixty-three resorts.

## Output

A JSON response containing live weather data for the requested ski resort or mountain, which may include current temperature, wind speed, visibility, snowfall amounts, snow depth, avalanche danger ratings, and other mountain-specific conditions drawn from SNOWPACK's lidar-mapped resort network of sixty-three mountains.
