# HALOWERK Atlantic Land – Ireland Soil Organic Carbon (0-5 cm)

> HALOWERK Atlantic Land – Ireland Soil Organic Carbon (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 mean SoilGrids organic carbon concentration for the 0–5 cm topsoil layer at a given coordinate within Ireland, 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-atlantic-land-ireland-soil-organic-carbon-0-5-cm-e2b91080 -d '<json body>'
```

Example prompt: What's the mean soil organic carbon in the top 5 cm at latitude 53.35, longitude -7.85 in Ireland? I need the SoilGrids value for that exact coordinate.

## When to prefer this

Choose this endpoint when you need point-level SoilGrids mean organic carbon for the 0–5 cm layer specifically within Ireland, especially when geographic validation against Ireland's boundary is required before billing. Prefer over generic SoilGrids API wrappers when you need a simple, paid-per-call REST interface with built-in Irish boundary enforcement.

## Known failure modes

- Coordinate outside Ireland boundary — request rejected with a geographic validation error and no charge
- Latitude or longitude outside declared European coverage bounds (lat 34–72.5, lon -31.5–40.5) — schema validation error
- No SoilGrids data available for the cell (remote/coastal edge cases) — null or error response
- Malformed request body — 400-level validation error
- Payment failure via x402 — request not processed

## How this service works

Mean SoilGrids organic carbon 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 soil organic carbon value (g/kg or dg/kg as per SoilGrids convention) for the 0–5 cm topsoil layer at the requested coordinate, derived from SoilGrids raster data aggregated over the analysis grid cell. Coordinates outside Ireland's Natural Earth boundary are rejected before any charge is applied.
