# HALOWERK Central Land – Austria Soil Texture Classifier

> HALOWERK Central Land – Austria 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 2026-09-13).

Returns the USDA soil texture class (e.g. loam, sandy clay) for a given coordinate in Austria, 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-austria-soil-texture-classifier-47fd3e65 -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 47.52 and longitude 14.13 in Austria? I need to know if it's sandy loam, clay, or something else for a land suitability report.

## When to prefer this

Choose this endpoint when you need USDA soil texture classification specifically for locations within Austria, backed by SoilGrids fractions with guaranteed boundary validation. It is purpose-built for Austria and rejects out-of-country coordinates before billing, making it more reliable than a general European soil endpoint for Austrian use cases.

## Known failure modes

- Coordinate outside Austria boundary — rejected with an error before payment is charged
- Coordinate within European coverage bounds but outside Austria — rejected by Natural Earth boundary validation
- Malformed or out-of-range latitude/longitude values — schema validation error
- SoilGrids upstream data unavailable for the queried cell — service error response
- Coordinate on water or non-soil area — may return null or error 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 Austria; results outside it are rejected before payment.

## Output

A USDA soil texture class label (e.g. 'sandy loam', 'clay loam', 'loam') for the queried coordinate, computed from SoilGrids sand, silt, and clay fraction data at the 0–5 cm depth layer. Coordinates outside the validated Austria boundary are rejected before any computation.
