# HALOWERK Central Land – Liechtenstein Soil Texture Classifier

> HALOWERK Central Land – Liechtenstein Soil Texture Classifier 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 USDA soil texture class (e.g. sandy loam, clay) for a given WGS84 coordinate within Liechtenstein, derived from SoilGrids sand, silt, and clay fractions.

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-texture-classifier-c378901e -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 47.14 and longitude 9.52 in Liechtenstein? I need to know whether it's sandy, loamy, or clayey for a land assessment.

## When to prefer this

Use this endpoint when you need a standardised USDA soil texture class for a specific point location within Liechtenstein and want it derived from the authoritative SoilGrids global dataset. Prefer it over manual GIS workflows or broader European soil APIs when you need per-point, low-latency, pay-per-call access with built-in geographic boundary validation.

## Known failure modes

- Coordinate outside Liechtenstein boundary → request rejected before payment with a boundary validation error
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon −31.5–40.5) → schema validation error
- Missing or malformed latitude/longitude → 400-level error
- SoilGrids upstream data unavailable for queried point → service error or empty result

## How this service works

USDA texture class calculated from SoilGrids sand, silt and clay fractions. The coordinate is validated against the Natural Earth boundary for Liechtenstein; results outside it are rejected before payment.

## Output

A USDA soil texture class label (e.g. 'sandy loam', 'silty clay loam') for the queried coordinate, derived from SoilGrids sand, silt, and clay fraction data for the 0–5 cm layer. Coordinates outside the Liechtenstein Natural Earth boundary are rejected before any charge is applied.
