# HALOWERK Central Land – Liechtenstein Soil Silt Fraction (0-5 cm)

> HALOWERK Central Land – Liechtenstein Soil Silt Fraction (0-5 cm) is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Returns the mean SoilGrids silt fraction for the 0–5 cm soil layer at a given coordinate within Liechtenstein, validated against Natural Earth boundaries.

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 halowerk-central-land-liechtenstein-soil-silt-fraction-0-5-cm-edf59f44 -d '<json body>'
```

Example prompt: What's the mean silt fraction in the top 0–5 cm of soil at latitude 47.14, longitude 9.52 in Liechtenstein?

## When to prefer this

Use this endpoint when you need SoilGrids-derived silt fraction data specifically for a point location within Liechtenstein, and want boundary validation before incurring payment costs. Prefer this over generic soil APIs when Liechtenstein-scoped validation, SoilGrids provenance, and per-call micropayment pricing are acceptable.

## Known failure modes

- Coordinate outside Liechtenstein boundary — request rejected before payment is processed
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Invalid or missing coordinate fields — schema validation failure
- SoilGrids data unavailable or no coverage for exact coordinate — null or error response

## How this service works

Mean SoilGrids silt fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Liechtenstein; results outside it are rejected before payment.

## Output

A numeric value representing the mean silt fraction (as a proportion or percentage) for the 0–5 cm soil depth at the specified coordinate, derived from SoilGrids data. Returns an error or rejection if the coordinate falls outside Liechtenstein's Natural Earth boundary.
