How this service works
Mean SoilGrids coarse-fragment volume for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Czechia; results outside it are rejected before payment.
Output
A numeric value representing the mean volumetric coarse-fragment content (%) in the 0–5 cm soil layer at the queried coordinate, derived from SoilGrids data, returned only if the coordinate falls within the Czechia boundary as validated by Natural Earth; coordinates outside the boundary are rejected before payment is charged.
Example use cases
Agricultural soil rockiness assessment
“I'm planning a crop field near Brno — can you check the topsoil coarse-fragment volume at latitude 49.19, longitude 16.61? I need to know how rocky or gravelly the surface layer is before I commit to cultivation.”
Construction site soil characterization
“We're doing a site survey in Olomouc at around 49.59 latitude and 17.25 longitude — can you pull the SoilGrids coarse-fragment percentage for the 0-5 cm layer so we can factor soil composition into our foundation planning?”
Environmental monitoring data enrichment
“For my environmental study I need the mean coarse-fragment volume for the topsoil at the coordinates 50.66 latitude, 14.05 longitude — this is a protected area in northern Bohemia and I want to compare soil texture across sample points.”

Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/cz-soil-coarse-fragmentsWhen to prefer
Choose this endpoint when you need SoilGrids coarse-fragment volume specifically for a point within Czechia and want boundary validation enforced server-side before payment. It is ideal for per-point lookups in agricultural, environmental, or construction workflows targeting Czech territory. Prefer it over generic SoilGrids API access when you want a pay-per-call micro-billing model and guaranteed rejection of out-of-bounds coordinates.
Side effects
- Coordinate outside Czechia boundary — request rejected before payment with a boundary validation error
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- No SoilGrids data available for the queried location — null or missing value response
- Malformed JSON input — 400 bad request
- Payment failure via x402 protocol — transaction not processed
