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-eastern-land-romania-soil-ph-lookup-3b11b8f8 -d '<json body>'
```

Example prompt: What's the SoilGrids topsoil pH (0–5 cm layer) at latitude 45.75, longitude 24.6 in Romania? I need the mean pH in H2O.

## When to prefer this

Choose this endpoint when you need point-level topsoil pH data specifically for a location within Romania and want SoilGrids-sourced values for the 0–5 cm layer. It is purpose-built for Romanian coordinates with boundary validation, making it more reliable than generic soil APIs that may return data for invalid or out-of-country coordinates. Prefer it over broader European soil endpoints when your use case is narrowly scoped to Romanian territory.

## Known failure modes

- Coordinate outside Romania boundary — request rejected before payment, error indicating out-of-bounds
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation error
- Network or upstream SoilGrids data unavailability — server error response

## 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 Romania; results outside it are rejected before payment.

## Output

Returns the mean SoilGrids pH value (in H2O) for the 0–5 cm topsoil layer at the requested coordinate. Coordinates outside Romania's Natural Earth boundary are rejected before any charge is applied.
