# SNOWPACK Know the Mountain

> SNOWPACK Know the Mountain is a paid API for AI agents from snowpack.fyi, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns lidar-mapped terrain data, live weather and snow conditions, avalanche danger, ski patrol/SOS info, and performance metrics for a ski resort at a given GPS coordinate across 63 resorts.

## 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-know-the-mountain-361e87e0
```

Example prompt: Pull up current snow conditions, avalanche danger, and trail info for the mountain near 39.6433° N, 106.3781° W — I want to know what I'm skiing into today.

## When to prefer this

Choose this endpoint when you need hyper-specific ski resort intelligence — including lidar terrain, avalanche danger, and verified emergency contacts — tied to a precise GPS location. It is superior to generic weather APIs for ski contexts because it combines terrain mapping, safety data, and live conditions in a single call. Best when the user is physically at or planning a trip to a ski mountain and needs actionable, safety-critical information.

## Known failure modes

- Coordinates not within range of any of the 63 supported resorts — no resort matched
- Missing required lat or lon query parameters — 400 Bad Request
- Resort data temporarily unavailable due to sensor or weather feed outage
- Payment not processed — 402 Payment Required (x402 protocol)
- Rate limit exceeded — 429 Too Many Requests

## 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 object containing lidar-mapped mountain and run data, real-time weather and snow conditions, current avalanche danger ratings, verified ski patrol and SOS contact info, and skiing performance measurements for the matched resort among 63 covered mountains.
