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

> HALOWERK Atlantic Land – Belgium Soil Sand 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 sand fraction (%) for the 0–5 cm depth 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-sand-fraction-0-5-cm-90e73739 -d '<json body>'
```

Example prompt: What's the mean sand fraction in the top 5 cm of soil at latitude 50.85 and longitude 4.35 in Belgium? I need the SoilGrids figure for a land parcel assessment.

## When to prefer this

Choose this endpoint when you need point-level SoilGrids sand fraction data specifically for locations within Belgium, and you want boundary validation built in (so you only pay for valid Belgian coordinates). Prefer it over generic SoilGrids API calls when you need a pay-per-call micropayment model via x402 with no API key management.

## Known failure modes

- Coordinate outside Belgium boundary: request rejected before payment with a boundary validation error
- Latitude or longitude out of the accepted European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation failure
- Missing required latitude or longitude field: request rejected with input validation error
- Network timeout or upstream SoilGrids data unavailability: service error response

## How this service works

Mean SoilGrids sand 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

A numeric value representing the mean sand fraction (as a percentage or proportion) of the 0–5 cm topsoil layer at the requested Belgian coordinate, derived from SoilGrids data. Coordinates outside Belgium's Natural Earth boundary are rejected before any payment is processed.
