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 Poland; results outside it are rejected before payment.
Output
A numeric value representing the mean coarse-fragment volume (volumetric %) derived from SoilGrids for the 0–5 cm soil layer at the requested coordinate. The coordinate is validated against Poland's Natural Earth boundary before processing; coordinates outside Poland are rejected prior to billing.
Example use cases
Agricultural suitability assessment for Polish farmland
“Can you look up the topsoil coarse-fragment volume at latitude 51.76, longitude 19.45 in Poland? I'm trying to assess whether the soil is too stony for arable farming.”
Geotechnical pre-survey for construction site
“I'm planning a construction project near Wrocław — can you get me the SoilGrids coarse-fragment percentage for the 0-5 cm layer at latitude 51.11, longitude 17.03?”
Environmental research data collection
“For my soil erosion study, I need the mean coarse-fragment volume at the 0–5 cm depth for a site at latitude 50.06, longitude 19.94 in southern Poland.”

Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-soil-coarse-fragmentsWhen to prefer
Choose this endpoint when you need point-level topsoil coarse-fragment data specifically within Poland and want a cost-effective per-call lookup ($0.004 USDC) with built-in boundary validation. Prefer it over raw SoilGrids API access when you need a pre-validated, pay-per-use microservice without managing SoilGrids authentication. Use sibling endpoints on baltikum.halowerk.com for complementary soil properties (clay, sand, bulk density) or terrain metrics at the same location.
Side effects
- Coordinate outside Poland boundary — request rejected before payment with a boundary validation error
- Latitude or longitude out of the European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed or missing coordinate fields — HTTP 400 bad request
- Service temporarily unavailable — HTTP 503
- Network timeout — no response returned within expected window
