How this service works
Mean SoilGrids clay fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Poland; results outside it are rejected before payment.
Output
A numeric value representing the mean clay fraction (likely as a percentage or volumetric fraction) in the 0–5 cm soil layer at the specified coordinate, sourced from SoilGrids. Coordinates outside Poland's Natural Earth boundary are rejected before the payment is processed.
Example use cases
Agricultural soil suitability assessment
“I'm evaluating a farm plot near Poznań at latitude 52.4064, longitude 16.9252 — can you tell me the clay fraction in the top 5 cm of soil there so I can assess if it's suitable for cereal crops?”
Construction ground condition check
“We're planning a foundation project at a site in Łódź, coordinates 51.7592° N, 19.4560° E — can you pull the topsoil clay percentage for that location so our engineers can review ground conditions?”
Environmental remediation site characterization
“For our soil contamination remediation study near Wrocław at 51.1079° N, 17.0385° E, what is the mean clay fraction in the 0 to 5 centimetre topsoil layer?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-soil-clayWhen to prefer
Use this endpoint when you need point-level clay fraction data specifically for Poland from the SoilGrids dataset, especially in workflows involving soil texture classification, agricultural planning, environmental assessment, or construction ground surveys. Prefer this over general geospatial APIs when you need a pre-validated, pay-per-call, boundary-checked soil property lookup with no authentication setup required.
Side effects
- Coordinate outside Poland's Natural Earth boundary — request rejected before payment, returns a boundary validation error
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Invalid or missing coordinate values — request rejected with input validation error
- Service unavailable or upstream SoilGrids data unreachable — returns a server error
