# HALOWERK Southern Land – Italy Soil Coarse Fragment Volume (0-5 cm)

> HALOWERK Southern Land – Italy Soil Coarse Fragment Volume (0-5 cm) is a paid API for AI agents from suedland.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-13).

Returns the mean SoilGrids coarse-fragment volume percentage for the 0–5 cm soil layer at a given coordinate validated to be within Italy.

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-southern-land-italy-soil-coarse-fragment-volume-0-5-cm-58527e32 -d '<json body>'
```

Example prompt: What's the mean coarse fragment volume in the top 5 cm of soil at latitude 43.77, longitude 11.25 in Italy?

## When to prefer this

Use this endpoint when you need point-level coarse-fragment volume data for Italian locations specifically, particularly when working with SoilGrids-derived soil texture metrics for agriculture, land evaluation, or environmental modeling. Prefer it over generic soil APIs when you need the 0–5 cm layer metric and Italian geographic validation is a feature rather than a constraint.

## Known failure modes

- Coordinate outside Italy boundary: request rejected before payment, error indicating location is out of coverage
- Latitude or longitude outside valid European range: schema validation failure
- Missing required latitude or longitude: request fails with validation error
- Network or upstream SoilGrids data unavailability: service may return 5xx error

## How this service works

Mean SoilGrids coarse-fragment volume for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Italy; results outside it are rejected before payment.

## Output

A numeric value representing the mean volumetric coarse-fragment content (percentage) for the 0–5 cm topsoil layer at the specified Italian coordinate, derived from SoilGrids. Coordinates outside Italy's Natural Earth boundary are rejected before the charge is applied.
