# HALOWERK Atlantic Land – Ireland Soil Clay Fraction (0-5 cm)

> HALOWERK Atlantic Land – Ireland Soil Clay Fraction (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 clay fraction for the 0–5 cm soil layer at a given WGS84 coordinate validated to be within Ireland's boundary.

## 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-clay-fraction-0-5-cm-907d12e8 -d '<json body>'
```

Example prompt: What's the SoilGrids clay fraction for the top 5 cm of soil at latitude 52.8, longitude -7.3 in Ireland?

## When to prefer this

Choose this endpoint when you need SoilGrids clay fraction specifically for a location within Ireland at the 0–5 cm depth layer. It is preferable when Ireland-scoped boundary validation is required before incurring cost, and when integrating soil texture data into agricultural, land valuation, or environmental workflows targeting Irish sites.

## Known failure modes

- Coordinate outside Ireland boundary — request rejected before payment with a validation error
- Coordinate within European coverage range but outside Ireland — boundary check fails
- Missing or invalid latitude/longitude values — schema validation error
- Coordinates at sea or outside any land boundary — rejected
- Service unavailability or upstream SoilGrids data gap for the queried location

## How this service works

Mean SoilGrids clay fraction 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

A numeric mean clay fraction value (likely as a percentage or volumetric proportion) for the 0–5 cm topsoil layer at the queried Irish coordinate, sourced from SoilGrids. Coordinates outside the Natural Earth boundary of Ireland are rejected before the payment is processed.
