# HALOWERK Atlantic Land – Luxembourg Soil Bulk Density (0-5 cm)

> HALOWERK Atlantic Land – Luxembourg Soil Bulk Density (0-5 cm) is a paid API for AI agents from atlantikland.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 within Luxembourg, validated against the 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-atlantic-land-luxembourg-soil-bulk-density-0-5-cm-4fdfdf7b -d '<json body>'
```

Example prompt: What's the mean topsoil bulk density (0-5 cm layer) at latitude 49.6116, longitude 6.1319 in Luxembourg? I need the SoilGrids value for that point.

## When to prefer this

Use this endpoint when you specifically need SoilGrids mean bulk density for the 0–5 cm topsoil layer at a precise coordinate within Luxembourg. It is ideal for soil science, agronomy, construction planning, and environmental analysis workflows that require standardized, globally comparable soil property data validated to the Luxembourg boundary. Prefer this over generic geospatial APIs when you need a specific, pay-per-call soil property value with boundary enforcement.

## Known failure modes

- Coordinate outside Luxembourg boundary — request is rejected before payment is processed
- Coordinates within European coverage range but outside Luxembourg polygon — boundary validation failure
- Invalid or missing latitude/longitude fields — schema validation error
- Coordinates at edge of European coverage limits rejected if outside Luxembourg
- Service unavailable or upstream SoilGrids data 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 Luxembourg; results outside it are rejected before payment.

## Output

A numeric mean bulk density value (from SoilGrids) for the 0–5 cm soil layer at the requested coordinate, or a rejection error if the coordinate falls outside Luxembourg's Natural Earth boundary.
