# HALOWERK Eastern Land – Hungary Soil Texture Classifier

> HALOWERK Eastern Land – Hungary Soil Texture Classifier is a paid API for AI agents from ostland.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 within Hungary, 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-eastern-land-hungary-soil-texture-classifier-7e06d4e9 -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 47.49 and longitude 19.04 in Hungary — is it sandy, loamy, or clay-dominant?

## When to prefer this

Choose this endpoint when you need a standardised USDA soil texture classification specifically for a point location within Hungary, backed by SoilGrids sand/silt/clay fractions. Prefer it over generic soil APIs when you need geographic validation against Hungary's official boundary and a per-call micropayment model with no subscription overhead.

## Known failure modes

- Coordinate outside Hungary's Natural Earth boundary — request rejected with a geographic validation error and no charge
- Latitude or longitude out of the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Network timeout or upstream SoilGrids data unavailability — service error returned
- Malformed or missing coordinate fields — request 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 Hungary; results outside it are rejected before payment.

## Output

Returns the USDA soil texture class (e.g. 'Sandy Clay Loam', 'Silty Clay', 'Loam') for the queried Hungarian coordinate, computed from SoilGrids-derived sand, silt, and clay fraction data. Coordinates outside Hungary's Natural Earth boundary are rejected before any charge is applied.
