# HALOWERK Central Land – Czechia Soil Texture Class

> HALOWERK Central Land – Czechia 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. sandy loam, clay) derived from SoilGrids sand, silt, and clay fractions for a WGS84 coordinate validated to fall within Czechia.

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-czechia-soil-texture-class-4ec22826 -d '<json body>'
```

Example prompt: What USDA soil texture class does SoilGrids report for the location at latitude 49.8175, longitude 15.4730 in Czechia — is it sandy, loamy, or clay-heavy?

## When to prefer this

Use this endpoint when you specifically need USDA soil texture classification for a point location within Czechia, derived from authoritative SoilGrids modelled fractions. It is preferable to generic soil APIs when you need a standardised USDA class label rather than raw fractions alone, and when the geographic scope is Czechia. For coordinates outside Czechia, sibling endpoints on the same host cover the broader Central European region. For raw SoilGrids sand/silt/clay fractions without classification, other sibling endpoints may be more appropriate.

## Known failure modes

- Coordinate outside Czechia boundary: request rejected before payment with a boundary-validation error
- Coordinate within European bounding box but outside Czechia polygon: rejected by Natural Earth boundary check
- SoilGrids upstream unavailability: may return a 502 or timeout error
- Latitude or longitude outside declared WGS84 ranges (34–72.5°N, −31.5–40.5°E): schema validation failure
- Missing required latitude or longitude field: 400 Bad Request

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

## Output

A USDA soil texture class label (e.g. 'Sandy loam', 'Clay', 'Silty clay loam') derived from the SoilGrids modelled sand, silt, and clay weight fractions for the 0–5 cm topsoil layer at the requested coordinate. Coordinates outside the Czechia boundary are rejected with an error before any charge is applied.
