# HALOWERK Central Land – Slovenia Soil Texture Class

> HALOWERK Central Land – Slovenia Soil Texture Class 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. clay loam, sandy loam) for a WGS84 coordinate in Slovenia, 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-slovenia-soil-texture-class-9f5bb56a -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 46.15, longitude 14.52 in Slovenia? I need to know if it's clay-heavy or more sandy for a site assessment.

## When to prefer this

Choose this endpoint when you specifically need USDA texture class for a point within Slovenia and want it derived from SoilGrids sand/silt/clay fractions. Prefer it over generic soil APIs when Slovenia-specific boundary validation and SoilGrids provenance are required. It pairs naturally with sibling endpoints on the same platform for pH, silt fraction, CEC, and elevation at the same coordinate.

## Known failure modes

- Coordinate outside Slovenia boundary — rejected with a geographic validation error before payment
- Latitude or longitude outside published European coverage range — schema validation error
- SoilGrids upstream data unavailable or missing for location — may return null or error
- Malformed request body — HTTP 400 bad request
- Payment not settled — HTTP 402 payment required

## 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 Slovenia; results outside it are rejected before payment.

## Output

Returns a USDA soil texture class label (e.g. 'sandy loam', 'clay', 'silty clay loam') derived from SoilGrids sand, silt, and clay fractions for the 0-5 cm layer at the queried coordinate. Coordinates outside Slovenia's Natural Earth boundary are rejected before processing.
