## 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-belgium-soil-bulk-density-0-5-cm-7f772aaa -d '<json body>'
```

Example prompt: What's the SoilGrids mean bulk density for the top 0–5 cm soil layer at latitude 50.85 and longitude 4.35 in Belgium?

## When to prefer this

Choose this endpoint when you need point-level SoilGrids bulk density specifically for the 0–5 cm topsoil layer within Belgium, particularly for agriculture, construction, environmental assessment, or land analysis workflows that require granular, standardized soil property data validated to Belgian territory.

## Known failure modes

- Coordinate outside Belgium boundary — request is rejected before payment is charged
- Latitude or longitude outside the accepted European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation error
- SoilGrids data unavailable or no-data cell at queried location — null or error response

## How this service works

Mean SoilGrids bulk density for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Belgium; results outside it are rejected before payment.

## Output

A numeric mean bulk density value (g/cm³ or kg/dm³) from SoilGrids for the 0–5 cm soil layer at the queried coordinate, returned only if the point falls within the validated Natural Earth boundary for Belgium.
