# HALOWERK Europe Land – Soil Sand Fraction (0-5 cm, Point)

> HALOWERK Europe Land – Soil Sand Fraction (0-5 cm, Point) is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Returns the mean SoilGrids sand fraction percentage for the 0–5 cm soil layer at a given European coordinate, evaluated over a 60-metre local analysis grid.

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-europe-land-soil-sand-fraction-0-5-cm-point-699a9266 -d '<json body>'
```

Example prompt: What's the SoilGrids sand fraction for the 0–5 cm soil layer at latitude 48.85 and longitude 2.35 in Europe? I need the 60-metre grid measurement from the HALOWERK Europe Land service.

## When to prefer this

Choose this endpoint when you need standardized, point-level topsoil sand fraction data for any location within the 30-country European coverage area, particularly for agriculture, land assessment, environmental science, or site suitability workflows. It is preferable over global soil APIs when European standardization and consistent units across countries are required, and over polygon-based siblings when only a single coordinate lookup is needed.

## Known failure modes

- Coordinate out of coverage bounds (latitude outside 34–72.5 or longitude outside -31.5–40.5) returns an error
- Non-European coordinates (e.g. North America, Asia) will be rejected
- Payment failure or invalid x402 payment header blocks the request
- Missing or malformed latitude/longitude values cause validation errors
- Coastal or offshore points may fall outside land coverage

## How this service works

Mean SoilGrids sand fraction for the 0-5 cm layer. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.

## Output

A standardized numerical value representing the mean sand fraction (as a percentage or volumetric fraction) in the 0–5 cm topsoil layer at the queried coordinate, derived from SoilGrids data and evaluated over a 60-metre local analysis grid. The result uses consistent units across all 30 covered European countries.
