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

> HALOWERK Atlantic Land – Ireland Soil Silt 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 silt fraction for the 0–5 cm soil layer at a given WGS84 coordinate within Ireland, validated against the Natural Earth 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-silt-fraction-0-5-cm-d7dc1f4a -d '<json body>'
```

Example prompt: What's the mean silt fraction in the top 5 cm of soil at latitude 52.67, longitude -8.63 in Ireland? I need the SoilGrids value for that location.

## When to prefer this

Use this endpoint when you specifically need SoilGrids silt fraction data for the 0–5 cm topsoil layer at a point location within Ireland. It is ideal for agricultural planning, soil texture analysis, environmental assessments, or land evaluation tasks where Ireland-bounded validation and micropayment-per-query access (via x402) are acceptable. Prefer this over general soil APIs when you need a low-cost, single-coordinate lookup with automatic geographic validation for Ireland.

## Known failure modes

- Coordinate outside Ireland boundary: request rejected before payment, error indicating the point is not within the Natural Earth Ireland polygon
- Latitude or longitude outside the published European coverage range (34–72.5°N, -31.5–40.5°E): validation error
- Malformed or missing coordinate fields: schema validation error
- Coordinate in a coastal or border ambiguity zone: may be rejected depending on boundary precision
- Network or upstream SoilGrids data unavailability: service error response

## How this service works

Mean SoilGrids silt 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 silt fraction value for the 0–5 cm soil layer at the queried coordinate, derived from SoilGrids. Coordinates outside the validated Ireland boundary are rejected before payment is charged.
