# HALOWERK Southern Land – Italy Soil Sand Fraction (0-5 cm)

> HALOWERK Southern Land – Italy Soil Sand Fraction (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 sand fraction for the 0-5 cm topsoil layer at a given WGS84 coordinate 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-sand-fraction-0-5-cm-481e5774 -d '<json body>'
```

Example prompt: What's the mean sand fraction in the top 5 cm of soil at latitude 43.77, longitude 11.25 in Tuscany, Italy?

## When to prefer this

Use this endpoint when you need a point-level topsoil sand fraction specifically for Italy, derived from the globally trusted SoilGrids dataset at the 0-5 cm depth. Prefer it over generic soil APIs when Italy-specific coordinate validation and pay-per-call pricing matter, or when integrating with other HALOWERK Southern Land endpoints for composite soil texture analysis (e.g. pairing with the CEC or USDA texture class endpoints on the same platform).

## Known failure modes

- Coordinate outside Italy boundary — request rejected before payment is processed
- Latitude or longitude out of accepted European range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed JSON body or missing required fields — bad request error
- Service unavailable or upstream SoilGrids data not accessible — server error

## How this service works

Mean SoilGrids sand fraction 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 sand fraction (typically as a percentage or volumetric fraction) for the 0-5 cm soil depth at the queried coordinate, valid only for points falling within the Natural Earth boundary of Italy.
