How this service works
Mean SoilGrids sand 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 mean sand fraction value (as measured by SoilGrids) for the 0–5 cm soil layer at the requested coordinate within Poland. The coordinate is first validated against the Natural Earth Poland boundary; requests outside Poland are rejected before any payment is processed.
Example use cases
Agricultural soil texture assessment
“I'm evaluating farmland near Poznań — can you get me the sand fraction of the topsoil (0–5 cm) at latitude 52.4069, longitude 16.9299 in Poland?”
Construction site ground suitability check
“We're scoping a building project in Kraków. What's the sand content in the top 5 cm of soil at coordinates 50.0647, 19.9450 in Poland?”
Environmental research soil sampling
“For my ecological study near Białystok, I need the mean sand fraction of the 0–5 cm soil layer at latitude 53.1325, longitude 23.1688 in Poland.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-soil-sandWhen to prefer
Use this endpoint when you need point-level topsoil sand fraction data specifically for locations within Poland and want automatic boundary validation before incurring a charge. Prefer it over generic SoilGrids API access when you need a lightweight, pay-per-call lookup with built-in Poland geofencing and no infrastructure overhead.
Side effects
- Coordinate outside Poland boundary — request rejected before payment with a boundary validation error
- Coordinate within European coverage range but outside Poland — returns rejection, no charge
- Latitude or longitude out of the accepted European range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- SoilGrids data unavailable for requested cell — may return null or error value
- Malformed request body — HTTP 400 bad request
