# HALOWERK Eastern Land – Cyprus Soil Silt Fraction (0–5 cm)

> HALOWERK Eastern Land – Cyprus Soil Silt Fraction (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 silt fraction for the 0–5 cm soil layer at a given coordinate within Cyprus, 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-eastern-land-cyprus-soil-silt-fraction-0-5-cm-655fbac2 -d '<json body>'
```

Example prompt: What's the mean silt fraction in the top 5 cm of soil at latitude 34.92, longitude 33.62 in Cyprus? I need the SoilGrids figure for that spot.

## When to prefer this

Choose this endpoint when you need the SoilGrids mean silt fraction specifically for the 0–5 cm topsoil layer at a point location within Cyprus. It is ideal for applications requiring Cyprus-scoped soil texture data (agriculture, land assessment, environmental modelling) where boundary validation before billing is important. Prefer this over generic SoilGrids API wrappers if you only need the Cyprus region and want a simple pay-per-call model with built-in geographic validation.

## Known failure modes

- Coordinate outside Cyprus boundary — request rejected before payment, error indicating location is out of bounds
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- No SoilGrids data available for the exact point — possible null or no-data response
- Malformed input (non-numeric coordinates) — schema validation error
- Network or upstream SoilGrids data service unavailability — 5xx error

## How this service works

Mean SoilGrids silt fraction 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 SoilGrids silt fraction (as a proportion or percentage) for the 0–5 cm soil depth layer at the requested coordinate. Coordinates outside the Cyprus boundary as defined by Natural Earth are rejected before the charge is applied.
