# HALOWERK Eastern Land – Cyprus Soil Coarse-Fragment Volume (0-5 cm)

> HALOWERK Eastern Land – Cyprus Soil Coarse-Fragment Volume (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 coarse-fragment volume (volumetric %) for the 0-5 cm soil layer at a given coordinate within Cyprus, 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-eastern-land-cyprus-soil-coarse-fragment-volume-0-5-cm-35e594c6 -d '<json body>'
```

Example prompt: What's the mean coarse-fragment volume in the top 5 cm of soil at latitude 34.92, longitude 33.02 in Cyprus?

## When to prefer this

Choose this endpoint when you need SoilGrids coarse-fragment volume specifically for a point location within Cyprus, particularly when you need built-in geographic validation that prevents charges for out-of-boundary queries. Prefer this over generic SoilGrids API access when you need a simple, per-call micropayment model and Cyprus-scoped validation.

## Known failure modes

- Coordinate outside Cyprus boundary — request rejected before payment, error returned
- Latitude or longitude outside allowed range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed or missing input coordinates — HTTP 4xx with validation message
- Upstream SoilGrids data unavailable — possible 5xx or timeout

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

## Output

Returns the mean volumetric coarse-fragment percentage for the 0–5 cm soil layer at the queried coordinate inside Cyprus. Coordinates outside the Cyprus Natural Earth boundary are rejected with an error before any charge is incurred.
