# HALOWERK Central Land – Liechtenstein Soil Sand Fraction (0–5 cm)

> HALOWERK Central Land – Liechtenstein Soil Sand Fraction (0–5 cm) is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-13).

Returns the mean SoilGrids sand fraction for the 0–5 cm soil layer at a given coordinate within Liechtenstein, validated against the country's Natural Earth boundary.

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-central-land-liechtenstein-soil-sand-fraction-0-5-cm-b56cf9b7 -d '<json body>'
```

Example prompt: What's the mean sand fraction in the top 5 cm of soil at latitude 47.14, longitude 9.52 in Liechtenstein? I need the SoilGrids value for that spot.

## When to prefer this

Choose this endpoint when you need surface-layer (0–5 cm) soil sand fraction data specifically for a point location within Liechtenstein, validated against official country boundaries. Prefer it over generic SoilGrids API calls when you need boundary-enforced, pay-per-call access without managing your own geospatial validation logic. Use sibling endpoints on the same host for other soil properties (pH, silt, CEC) or terrain metrics at the same location.

## Known failure modes

- Coordinate outside Liechtenstein's Natural Earth boundary — request rejected before payment
- Latitude or longitude outside the declared European coverage range (34–72.5°N, -31.5–40.5°E) — validation error
- Missing required latitude or longitude fields — schema validation error
- SoilGrids data unavailable for the exact location — no-data response
- Payment failure via x402 protocol — call not processed

## How this service works

Mean SoilGrids sand fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Liechtenstein; results outside it are rejected before payment.

## Output

A numeric value representing the mean sand fraction (as a proportion or percentage) in the 0–5 cm soil layer at the queried coordinate, sourced from the SoilGrids dataset. Coordinates outside Liechtenstein's Natural Earth boundary are rejected without charge.
