# HALOWERK Central Land – Liechtenstein Soil Coarse-Fragment Volume (0-5 cm)

> HALOWERK Central Land – Liechtenstein Soil Coarse-Fragment Volume (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 2026-09-15).

Returns the mean SoilGrids coarse-fragment volume (volumetric %) for the 0-5 cm soil layer at a given coordinate within Liechtenstein, validated against Natural Earth boundaries.

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-coarse-fragment-volume-0-5-cm-7e22a6eb -d '<json body>'
```

Example prompt: What's the coarse-fragment volume of the topsoil (0-5 cm) at latitude 47.14 and longitude 9.52 in Liechtenstein? I need the SoilGrids value for that point.

## When to prefer this

Choose this endpoint when you need a precise, point-level SoilGrids coarse-fragment volume for the topsoil layer specifically within Liechtenstein. It is ideal for micro-geographic analyses, environmental assessments, or GIS data enrichment pipelines focused on that country. If you need coarse-fragment data for other Central European countries, check sibling endpoints on the same host. Prefer this over generic soil APIs when Liechtenstein boundary validation is required to ensure data integrity.

## Known failure modes

- Coordinate outside Liechtenstein boundary: request rejected before payment, likely returns a 422 or 400 error with a boundary-validation message
- Coordinate outside the declared European coverage box (lat 34–72.5, lon -31.5–40.5): schema validation error
- Missing or malformed latitude/longitude: 400 bad request
- Payment failure (x402): transaction not completed, no result returned
- No SoilGrids data available for the queried point: may return null or data-not-found response

## 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 Liechtenstein; results outside it are rejected before payment.

## Output

A numeric value representing the mean volumetric coarse-fragment content (percentage by volume) of the 0-5 cm soil layer at the queried coordinate, derived from SoilGrids. The endpoint first validates the coordinate falls within Liechtenstein's Natural Earth boundary and rejects out-of-bounds requests before processing or charging.
