# HALOWERK Atlantic Land – Ireland Soil Coarse-Fragment Volume (0-5 cm)

> HALOWERK Atlantic Land – Ireland Soil Coarse-Fragment Volume (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 coarse-fragment volume (%) for the 0–5 cm soil layer at a given coordinate validated to be within Ireland.

## 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-ireland-soil-coarse-fragment-volume-0-5-cm-32002160 -d '<json body>'
```

Example prompt: What's the mean coarse-fragment volume in the top 5 cm of soil at latitude 53.35, longitude -6.26 in Ireland? I need the SoilGrids figure for a land parcel assessment.

## When to prefer this

Choose this endpoint when you need machine-readable SoilGrids coarse-fragment volume specifically for a point location within Ireland, with built-in boundary validation ensuring you only pay for in-scope coordinates. Prefer it over generic SoilGrids API access when you want a simple pay-per-call micropayment model with no subscription, or when building agentic workflows that assess Irish land parcels for agriculture, construction, or environmental purposes.

## Known failure modes

- Coordinate outside Ireland boundary – request rejected before payment, error indicating invalid location
- Coordinate within European coverage range but outside Ireland polygon – rejected with boundary validation error
- Malformed or out-of-range latitude/longitude values – validation error (lat: 34–72.5, lon: -31.5–40.5)
- SoilGrids data unavailable for remote or coastal edge coordinates – may return null or no-data value
- Payment failure via x402 protocol – request not processed

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

## Output

Returns the mean coarse-fragment volume (volumetric %) derived from SoilGrids for the 0–5 cm soil depth at the specified coordinate. The coordinate is validated against the Natural Earth boundary for Ireland; requests falling outside Ireland are rejected before any charge is applied.
