# HALOWERK Europe Land – SoilGrids Sand Fraction 0-5cm (1,000m Buffer)

> HALOWERK Europe Land – SoilGrids Sand Fraction 0-5cm (1,000m Buffer) is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-15).

Returns the mean SoilGrids sand fraction for the 0-5 cm soil layer evaluated over a 1,000-metre circular neighbourhood around a given European coordinate.

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-soilgrids-sand-fraction-0-5cm-1-000m-buffer-8b3979ac -d '<json body>'
```

Example prompt: What's the mean sand fraction in the top 5 cm of soil within a 1 km radius of latitude 51.5 and longitude 4.2 in Europe?

## When to prefer this

Choose this endpoint when you need a broad landscape-scale (1 km radius) soil sand fraction estimate for a single European coordinate, as opposed to the 60-metre local-analysis variant which is better suited for precise, small-area queries. Ideal for regional land assessment, agricultural planning, or environmental modelling where neighbourhood-level soil texture matters more than hyper-local point values.

## Known failure modes

- Coordinate outside the supported European bounding box (lat 34–72.5, lon -31.5–40.5) returns an error or empty result
- Invalid latitude/longitude types or missing required fields cause a 400-level validation error
- No SoilGrids coverage for extremely remote or polar-edge coordinates may return null or no-data values
- Payment failure via x402 protocol prevents call execution
- Network timeouts if the spatial aggregation computation exceeds response limits

## How this service works

Mean SoilGrids sand fraction for the 0-5 cm layer. The service evaluates a circular 1,000 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.

## Output

A standardized numerical value representing the mean sand fraction (as a proportion or percentage) in the 0-5 cm soil depth layer, spatially averaged over a 1,000-metre circular buffer around the supplied coordinate, sourced from SoilGrids global soil data.
