How this service works
Mean SoilGrids cation exchange capacity for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Croatia; results outside it are rejected before payment.
Output
A numeric mean cation exchange capacity value (in cmolc/kg) derived from SoilGrids for the 0-5 cm soil depth at the queried coordinate, restricted to validated points within Croatia's Natural Earth boundary.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a field in Croatia near Osijek — coordinates 45.56 latitude, 18.69 longitude — can you pull the topsoil cation exchange capacity from SoilGrids so I know how well it retains nutrients?”
Precision farming soil nutrient mapping
“For my Croatian vineyard site at 45.81° N, 16.02° E, can you get the mean SoilGrids CEC for the 0 to 5 centimeter soil layer so I can plan fertilizer inputs?”
Environmental baseline data collection
“I need to build a soil chemistry baseline for a conservation project in Croatia — can you fetch the cation exchange capacity for the topsoil layer at 44.12 latitude, 15.87 longitude?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hr-soil-cecWhen to prefer
Choose this endpoint when you need a fast, pay-per-call lookup of SoilGrids topsoil cation exchange capacity specifically for a point coordinate within Croatia, and want built-in boundary validation so out-of-region requests are rejected before incurring charges. Prefer it over generic SoilGrids API access when you only need CEC at 0-5 cm depth and want a minimal, cost-effective micro-API with x402 payment integration.
Side effects
- Coordinate outside Croatia's Natural Earth boundary — request rejected before payment
- Latitude or longitude outside European coverage bounds (34–72.5°N, -31.5–40.5°E) — validation error
- Malformed JSON body or missing required fields — 400 error
- Payment failure or insufficient USDC balance — 402 error
- SoilGrids upstream data unavailable for remote or coastal edge pixels — null or error response
