# HALOWERK Atlantic Land – Belgium Soil Silt Fraction (0-5 cm)

> HALOWERK Atlantic Land – Belgium Soil Silt Fraction (0-5 cm) is a paid API for AI agents from atlantikland.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Returns the mean SoilGrids silt fraction for the 0-5 cm soil layer at a given WGS84 coordinate within Belgium.

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-belgium-soil-silt-fraction-0-5-cm-f4fe5251 -d '<json body>'
```

Example prompt: What's the mean silt fraction in the top 5 cm of soil at latitude 50.85 and longitude 4.35 in Belgium? I need the SoilGrids value for that location.

## When to prefer this

Choose this endpoint when you need point-level topsoil silt fraction data specifically for Belgian locations, validated against the Natural Earth boundary, and billed per-call via x402 micropayments. It is ideal for agents automating land assessment, agricultural analysis, or environmental profiling workflows in Belgium where SoilGrids silt data at the 0-5 cm depth is required.

## Known failure modes

- Coordinate outside Belgium boundary – request rejected before payment with a validation error
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5) – rejected with schema validation error
- Non-numeric or missing coordinate values – bad request error
- Service unavailable – upstream SoilGrids data unreachable

## How this service works

Mean SoilGrids silt fraction 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

Returns the mean SoilGrids silt fraction value (likely as a percentage or g/kg ratio) for the 0-5 cm topsoil layer at the queried Belgian coordinate. Coordinates outside the Belgium boundary are rejected before any charge is made.
