## 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-silt-fraction-0-5-cm-662daa24 -d '<json body>'
```

Example prompt: What's the SoilGrids mean silt fraction for the topsoil layer at latitude 49.6116, longitude 6.1319 in Luxembourg?

## When to prefer this

Choose this endpoint when you need precise, point-level SoilGrids silt fraction data specifically for locations within Luxembourg. It is ideal when you are building land analysis pipelines, agricultural suitability models, or environmental assessments scoped to Luxembourg and need the surface soil texture component without querying a broader global API. The built-in boundary validation ensures you are only charged for valid Luxembourg coordinates.

## Known failure modes

- Coordinate falls outside Luxembourg boundary — request rejected before payment with a boundary validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- No SoilGrids data available for the exact coordinate — may return null or a data-gap error
- Malformed or missing latitude/longitude fields — input validation error
- Payment failure via x402 protocol — request not processed

## How this service works

Mean SoilGrids silt fraction 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 numeric mean silt fraction value for the 0–5 cm soil layer at the queried coordinate, derived from SoilGrids data. The coordinate is pre-validated against Luxembourg's Natural Earth boundary; requests outside Luxembourg are rejected before any charge is incurred.
