# HALOWERK Southern Land ES Soil Texture

> HALOWERK Southern Land ES Soil Texture 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 (e.g. sandy loam, clay) for a WGS84 coordinate in Spain, 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-southern-land-es-soil-texture-83490972 -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 37.8 longitude -5.2 in Spain? I need to know if the soil is sandy, loamy, or clay for a land evaluation.

## When to prefer this

Use this endpoint when you need USDA soil texture classification specifically for a coordinate in Spain, and want a lightweight, pay-per-call lookup backed by SoilGrids data. Prefer this over downloading raw SoilGrids rasters when you need a single-point, human-readable texture class (e.g. sandy loam, silty clay) without processing sand/silt/clay fractions yourself. The built-in Spain boundary validation prevents wasted calls for out-of-range coordinates.

## Known failure modes

- Coordinate outside Spain boundary — rejected with an error before payment, no charge incurred
- Latitude or longitude out of accepted range (lat 34–72.5, lon -31.5–40.5) — validation error
- SoilGrids data unavailable for the location — service error
- Malformed request body — schema validation error
- Payment failure for x402 micropayment — transaction not processed

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

## Output

The USDA soil texture class for the queried Spanish coordinate, derived from SoilGrids sand, silt, and clay fraction data at the 0-5 cm depth layer. Coordinates outside Spain's Natural Earth boundary are rejected before any charge is applied.
