# HALOWERK Central Land – Liechtenstein Soil Bulk Density (0-5 cm)

> HALOWERK Central Land – Liechtenstein Soil Bulk Density (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 mean SoilGrids bulk density for the 0–5 cm soil layer at a WGS84 coordinate validated against Liechtenstein's 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-bulk-density-0-5-cm-e56fe0a5 -d '<json body>'
```

Example prompt: What's the SoilGrids bulk density for the top 0–5 cm of soil at latitude 47.14, longitude 9.52 in Liechtenstein?

## When to prefer this

Use this endpoint when you specifically need SoilGrids mean bulk density for the topmost (0–5 cm) soil layer at a point location within Liechtenstein. It is the right choice when boundary validation against Liechtenstein is required before incurring a charge, and when the use case involves soil science, agriculture, hydrology, or land-use planning in that country. Prefer sibling endpoints for other soil properties (pH, silt, CEC) or terrain metrics at the same location.

## Known failure modes

- Coordinate outside Liechtenstein boundary — request rejected before payment is processed
- Latitude or longitude outside the European coverage range (34–72.5°N, -31.5–40.5°E) — schema validation error
- Malformed or missing latitude/longitude fields — input validation failure
- Network or upstream SoilGrids data unavailability — service error

## How this service works

Mean SoilGrids bulk density 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 mean bulk density value (g/cm³ or kg/m³) from SoilGrids for the 0–5 cm soil layer at the specified coordinate. Returns an error or rejection if the coordinate falls outside the validated Liechtenstein boundary.
