# HALOWERK Europe Land – Soil pH Point (60m Grid)

> HALOWERK Europe Land – Soil pH Point (60m Grid) is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Returns the mean SoilGrids pH in H2O for the 0–5 cm soil layer at a given European coordinate, evaluated over a 60-metre local analysis grid.

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-europe-land-soil-ph-point-60m-grid-8768a8db -d '<json body>'
```

Example prompt: What's the soil pH in the top 5 centimetres at latitude 51.5, longitude -0.1 in the UK? I need the SoilGrids H2O reading for a 60-metre grid around that point.

## When to prefer this

Choose this endpoint when you need a precise, point-level soil pH reading for a European location and want a standardized H2O-method value from SoilGrids evaluated at 60-metre resolution. It is ideal for agricultural planning, environmental assessments, or ecological research across Europe where topsoil acidity data is required. Prefer this over polygon-based variants when you have a single coordinate and do not need area-averaged results.

## Known failure modes

- Coordinate outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) returns an error or empty result
- Coordinate in a marine or water-body area with no soil data may return null or error
- Malformed or missing latitude/longitude values cause a validation error
- Service unavailability or upstream SoilGrids data gaps may cause a timeout or empty response

## How this service works

Mean SoilGrids pH in H2O for the 0-5 cm layer. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.

## Output

A standardized soil pH value (H2O method) representing the mean pH of the 0–5 cm topsoil layer, derived from SoilGrids data and evaluated over a 60-metre local analysis grid centred on the supplied coordinate. Coverage spans 30 European countries.
