How this service works
Mean SoilGrids clay fraction 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 clay fraction (likely as a percentage or volumetric fraction) for the 0–5 cm topsoil layer at the queried coordinate, derived from SoilGrids data, validated to fall within the Natural Earth boundary of Czechia.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a farm plot near Brno — can you check the topsoil clay fraction at latitude 49.19, longitude 16.61 so I know how clay-heavy the soil is?”
Construction site soil texture check
“We're planning a building project at latitude 50.76, longitude 15.05 in the Czech Republic — what's the clay content in the top 5 cm of soil there?”
Environmental research soil profiling
“For my soil texture study in northern Bohemia, I need the SoilGrids clay fraction at 0–5 cm depth for the coordinate 50.65 latitude, 13.38 longitude.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/cz-soil-clayWhen to prefer
Use this endpoint when you need precise, point-level topsoil clay fraction data specifically for locations within Czechia, backed by SoilGrids global soil data. Prefer it over generic soil APIs when you need the 0–5 cm depth layer specifically and want boundary-validated results to avoid erroneous out-of-region lookups. It pairs well with sibling endpoints on the same platform for silt, pH, and CEC to build a complete soil texture profile.
Side effects
- Coordinate outside Czechia boundary — rejected before payment with an error indicating the point is not within the validated region
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed request body or missing required fields — 400-level error
- Payment failure or insufficient USDC balance — x402 payment required error
- Service unavailability or upstream SoilGrids data issue — 5xx error
