# HALOWERK Southern Land – Italy Soil Bulk Density (0-5 cm)

> HALOWERK Southern Land – Italy Soil Bulk Density (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 2026-09-15).

Returns the mean SoilGrids bulk density for the 0–5 cm soil layer at a given coordinate, validated to lie within Italy's boundary.

## 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-bulk-density-0-5-cm-d7eb2f00 -d '<json body>'
```

Example prompt: What's the mean soil bulk density in the top 5 centimeters at latitude 43.7696 and longitude 11.2558 in Italy?

## When to prefer this

Choose this endpoint when you specifically need surface-layer (0-5 cm) bulk density for a point location within Italy, sourced from the SoilGrids dataset, with automatic boundary validation to avoid out-of-area charges. Prefer it over generic soil APIs when working on Italian land assessment, agricultural analysis, or environmental screening workflows where per-call cost efficiency matters.

## Known failure modes

- Coordinate outside Italy boundary — rejected before payment with a geographic validation error
- Latitude or longitude out of the allowed European coverage range — schema validation error
- Malformed request body — HTTP 400 bad request
- Service unavailable or upstream SoilGrids data issue — HTTP 500 or timeout

## How this service works

Mean SoilGrids bulk density 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 SoilGrids bulk density (g/cm³ or kg/dm³) for the 0–5 cm soil layer at the specified coordinate. Coordinates outside Italy's Natural Earth boundary are rejected before payment is processed.
