How this service works
Mean SoilGrids clay fraction for the 0-5 cm layer. The service evaluates a circular 250 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A single numeric value representing the mean clay fraction (standardized units, typically g/kg or % clay) for the 0–5 cm soil depth layer, averaged over a 250-metre circular buffer around the supplied coordinate. Coverage spans 30 European countries.
Example use cases
Agricultural soil suitability assessment
“Can you check the clay fraction in the top 5cm of soil around latitude 47.8, longitude 16.5 in Austria? I'm evaluating whether the land is suitable for growing wheat.”
Construction ground assessment
“I need to know the mean clay content of the topsoil within 250 metres of coordinates 43.6, 1.4 in southern France — we're planning a building project and need to understand soil composition.”
Environmental land characterisation
“Pull the SoilGrids clay fraction for the 0 to 5 centimetre layer at latitude 52.1, longitude 21.0 in Poland — I'm building a land quality dataset for a European nature restoration project.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-soil-clay-buffer-250mWhen to prefer
Choose this endpoint when you need topsoil clay content specifically for a point location in Europe and want a spatially averaged (250m buffer) result rather than a raw pixel value or polygon-based estimate. It is ideal for site-level soil characterisation, agricultural planning, and land suitability analysis across any of the 30 covered European countries. Prefer sibling endpoints for other soil properties (pH) or other land cover metrics (cropland, grassland, tree cover).
Side effects
- Coordinate outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) returns an error
- Invalid or missing latitude/longitude values cause a validation error
- Coordinates in areas with no SoilGrids data coverage may return null or incomplete results
- Payment failure via x402 protocol prevents the call from being processed
