How this service works
Mean SoilGrids sand 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 numeric value representing the mean SoilGrids sand fraction (standardized units) for the 0–5 cm soil depth layer, averaged over a 250-metre circular neighbourhood centred on the supplied WGS84 coordinate. Covers 30 European countries.
Example use cases
Agricultural soil texture screening
“I'm evaluating a farm parcel near Seville, Spain — can you check the topsoil sand fraction at latitude 37.39, longitude -5.99 using the 250-metre buffer so I know if the soil is sandy enough for drip irrigation?”
Construction ground survey pre-check
“We have a potential building site at latitude 52.37, longitude 4.90 near Amsterdam. Can you pull the SoilGrids sand content for the top 5 cm of soil across the 250-metre neighbourhood to inform our foundation assessment?”
Environmental land classification pipeline
“I'm running a land suitability model across multiple European sites. For the coordinate at latitude 43.60, longitude 1.44 near Toulouse, fetch the mean sand fraction in the 0–5 cm layer from the 250 m buffer and give me the standardized value.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-soil-sand-buffer-250mWhen to prefer
Choose this endpoint when you need a spatially smoothed (250 m buffer) topsoil sand fraction estimate at a specific European point, derived from the globally consistent SoilGrids dataset, rather than raw pixel values or a different buffer size. Prefer it over the 60 m buffer sibling when site-level noise reduction is important and over polygon-based siblings when only a coordinate is available.
Side effects
- Coordinate outside European coverage (lat 34–72.5, lon -31.5–40.5) returns an error or null
- Invalid or missing latitude/longitude fields return a validation error
- Payment failure or insufficient USDC balance blocks the request (x402 protocol)
- Service unavailability returns a 5xx error with no soil data
