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

> HALOWERK Atlantic Land – Ireland Soil pH (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 2026-09-13).

Returns the mean SoilGrids pH in H2O for the 0–5 cm soil layer at a given coordinate within Ireland, validated against the Natural Earth Ireland 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-ph-0-5-cm-8422c86a -d '<json body>'
```

Example prompt: What's the mean soil pH in the top 5 centimetres at latitude 53.35, longitude -6.26 in Ireland?

## When to prefer this

Choose this endpoint when you need point-level topsoil pH data specifically for locations within Ireland, and want built-in boundary validation to avoid billing errors for out-of-bounds coordinates. It is ideal for land assessment workflows, agricultural planning, or environmental reporting pipelines targeting Irish sites. Prefer it over generic SoilGrids API calls when you want a pre-validated, pay-per-query microservice with minimal integration overhead.

## Known failure modes

- Coordinate outside Ireland boundary: request rejected before payment with a validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation failure
- Malformed or missing coordinate fields: HTTP 422 or 400 bad request
- SoilGrids data unavailable for the location: may return null or error response
- Payment failure (x402 protocol): request not processed

## How this service works

Mean SoilGrids pH in H2O 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 pH value (pH in H2O scale) for the 0–5 cm depth layer at the submitted Irish coordinate, drawn from SoilGrids data. The coordinate is first validated against the Natural Earth Ireland boundary; requests falling outside Ireland are rejected before any charge is applied.
