# HALOWERK Southern Land – Greece Soil Texture Classifier

> HALOWERK Southern Land – Greece Soil Texture Classifier is a paid API for AI agents from suedland.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Returns the USDA soil texture class for a given coordinate in Greece, derived from SoilGrids sand, silt, and clay fractions for the 0–5 cm layer.

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-southern-land-greece-soil-texture-classifier-bd86f6fb -d '<json body>'
```

Example prompt: What is the USDA soil texture class at latitude 37.97 and longitude 23.73 in Greece — the kind derived from SoilGrids sand, silt, and clay fractions?

## When to prefer this

Choose this endpoint when you need a standardised USDA soil texture category for a specific point in Greece and want the classification pre-computed from SoilGrids sand, silt, and clay fractions without running your own pedotransfer functions. It is ideal for agricultural planning, land valuation, environmental reporting, or precision agriculture workflows scoped to Greece. Prefer it over raw SoilGrids fraction endpoints (available as siblings) when a ready-made texture class label — not individual fraction values — is what your pipeline needs.

## Known failure modes

- Coordinate outside Greece boundary → rejected before payment, returns a boundary validation error
- Latitude or longitude outside published European range (lat 34–72.5, lon -31.5–40.5) → schema validation error
- SoilGrids data unavailable or missing for the pixel → may return null or error response
- Malformed or missing coordinate fields → request rejected with input validation error

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

## Output

A USDA soil texture class label (e.g. 'Sandy Loam', 'Clay', 'Silt Loam') derived from the SoilGrids 0–5 cm sand, silt, and clay fraction means at the specified Greek coordinate. Coordinates outside the validated Natural Earth boundary for Greece are rejected before any computation or payment occurs.
