# HALOWERK Atlantic Land – Netherlands Soil Texture Classification

> HALOWERK Atlantic Land – Netherlands Soil Texture Classification 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. clay, loam, sandy loam) for a given coordinate in the Netherlands, 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-netherlands-soil-texture-classification-b84d8d55 -d '<json body>'
```

Example prompt: What's the USDA soil texture class at latitude 52.37, longitude 4.89 in the Netherlands? I need to know whether the soil is sandy, loamy, or clay-dominant for a land assessment.

## When to prefer this

Choose this endpoint when you need a single, authoritative USDA soil texture classification for a specific point in the Netherlands and want a low-cost ($0.004/call) lookup rather than downloading and processing raw SoilGrids rasters yourself. It is ideal for agent workflows that need to enrich land parcel data with soil type programmatically. If you need soil properties outside the Netherlands or other soil metrics (e.g. CEC, organic carbon), use the sibling endpoints on the same platform.

## Known failure modes

- Coordinate outside Netherlands boundary: request rejected with an error before payment, no charge applied
- Latitude or longitude outside the accepted European coverage range (lat 34–72.5, lon -31.5–40.5): validation error
- SoilGrids data unavailable for the specific coordinate (e.g. water body, no data coverage): returns error or no-data response
- Malformed input (missing latitude or longitude): schema 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 Netherlands; results outside it are rejected before payment.

## Output

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