# HALOWERK Atlantic Land – Belgium Soil Texture Classifier

> HALOWERK Atlantic Land – Belgium Soil Texture Classifier is a paid API for AI agents from atlantikland.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 Belgium, 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-atlantic-land-belgium-soil-texture-classifier-2ba9d33f -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 50.85 and longitude 4.35 in Belgium — is it sandy loam, clay, or something else according to SoilGrids data?

## When to prefer this

Choose this endpoint when you need the official USDA soil texture classification for a specific point in Belgium derived from the SoilGrids global dataset, particularly for agricultural planning, land assessment, or environmental modeling workflows scoped to Belgium. It is preferable to general soil APIs when you need Belgium-specific boundary validation and a ready-made USDA texture class rather than raw fraction values alone.

## Known failure modes

- Coordinate falls outside Belgium's validated boundary — request rejected before payment, error indicating out-of-coverage area
- Latitude or longitude outside the published European coverage range (34–72.5°N, 31.5°W–40.5°E) — schema validation error
- SoilGrids upstream data unavailable or null for the queried pixel — may return no-data response
- Malformed input (non-numeric coordinates) — validation error returned
- Network timeout or service unavailability — HTTP 5xx 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 Belgium; results outside it are rejected before payment.

## Output

Returns the USDA soil texture class (e.g. 'Sandy Clay Loam', 'Silty Clay') computed from the SoilGrids-derived proportions of sand, silt, and clay at the queried point. May also include the underlying fraction values. Coordinates outside Belgium's Natural Earth boundary are rejected before the payment is processed.
