# HALOWERK Eastern Land – Cyprus Soil Bulk Density (0-5 cm)

> HALOWERK Eastern Land – Cyprus Soil Bulk Density (0-5 cm) is a paid API for AI agents from ostland.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 Cyprus, validated against the Natural Earth Cyprus 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-eastern-land-cyprus-soil-bulk-density-0-5-cm-1df24e7d -d '<json body>'
```

Example prompt: What's the mean bulk density of the topsoil (0-5 cm layer) at latitude 34.85, longitude 33.02 in Cyprus?

## When to prefer this

Choose this endpoint when you need official SoilGrids bulk density data specifically for a point location within Cyprus and need coordinate validation enforced before incurring a charge. Prefer it over generic soil APIs when Cyprus-boundary enforcement and per-call micropayment pricing (x402) fit your workflow.

## Known failure modes

- Coordinate outside Cyprus boundary — request rejected before payment, returns boundary validation error
- Coordinate within valid longitude/latitude range but outside Cyprus — rejected by Natural Earth polygon check
- Malformed or missing latitude/longitude — returns input validation error
- SoilGrids upstream data unavailable for the given cell — may return no-data value or service error
- Coordinate on coastline edge — boundary check may reject marginal cases

## How this service works

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

## Output

A numeric mean bulk density value (g/cm³ or kg/dm³) for the 0-5 cm topsoil layer at the requested coordinate, sourced from SoilGrids. Coordinates outside the Cyprus Natural Earth boundary are rejected before any charge is applied.
