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-luxembourg-soil-organic-carbon-0-5-cm-218c2327 -d '<json body>'
```

Example prompt: What's the mean soil organic carbon in the 0-5 cm layer at latitude 49.6116, longitude 6.1319 in Luxembourg?

## When to prefer this

Choose this endpoint when you need the SoilGrids mean organic carbon value specifically for the 0-5 cm topsoil layer at a point location within Luxembourg. It is ideal for land assessment, agricultural analysis, environmental reporting, or real estate due diligence workflows focused on Luxembourg. The built-in boundary validation ensures you are only charged for valid Luxembourg coordinates. Use sibling endpoints on the same provider for related soil or terrain metrics (e.g. cation exchange capacity, slope, built-up area).

## Known failure modes

- Coordinate outside Luxembourg boundary — request rejected before payment, with a boundary validation error
- Latitude or longitude outside the European coverage bounds (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Missing or malformed latitude/longitude fields — input schema validation failure
- Service unavailability or upstream SoilGrids data issues — 5xx error

## How this service works

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

## Output

A mean soil organic carbon value (from SoilGrids) for the 0-5 cm depth layer at the queried coordinate. The coordinate is pre-validated against the Luxembourg Natural Earth boundary; requests outside Luxembourg are rejected before any charge is applied.
