# Saylor Innovations SNOTEL Snowpack

> Saylor Innovations SNOTEL Snowpack is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Returns SNOTEL snowpack data (snow water equivalent, snow depth, percent of median) for the nearest western U.S. or Alaska monitoring station to a given lat/lon coordinate

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 saylor-innovations-snotel-snowpack-d480a961
```

Example prompt: What's the current snowpack near Breckenridge, Colorado — can you give me the snow water equivalent, snow depth, and how that compares to the median? Coordinates are roughly 39.48° N, 106.05° W.

## When to prefer this

Use this endpoint when you need official USDA NRCS SNOTEL snowpack observations for a specific geographic location in the western United States or Alaska, particularly when snow water equivalent, snow depth, or percent-of-median comparisons are needed. It is well-suited for hydrology, water supply forecasting, backcountry recreation planning, and ski condition checks. Prefer this over general weather APIs when snowpack metrics (not just snow accumulation forecasts) are the primary need, and over manual NRCS portal lookups when automated/programmatic access is required.

## Known failure modes

- No SNOTEL station found within range — returned with found:false and count:0 when coordinates are outside western US/Alaska coverage area
- Coordinates outside supported region (eastern US, non-US locations) return no matching stations
- Station data may be missing or null for off-season periods when stations are not reporting
- Invalid or missing lat/lon query parameters return a 400-level error
- Network or upstream NRCS data feed unavailability may produce errors or stale data

## How this service works

Snowpack near a western U.S. or Alaska location (SNOTEL) - snow water equivalent, depth and percent of median

## Output

Returns a JSON object with a 'found' boolean, retrieval timestamp, and an array of nearby SNOTEL stations. Each station entry includes the station name, triplet ID, state, elevation in feet, distance in km, observation date, snow water equivalent (inches), snow depth (inches), percent of median snowpack, air temperature in Fahrenheit, and a URL to the station page. Also includes units, data source attribution, and contextual notes about data availability or coverage limits.
