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 Bulgaria; results outside it are rejected before payment.
Output
A numeric mean cation exchange capacity value (cmolc/kg) from SoilGrids for the 0–5 cm depth layer at the requested Bulgarian coordinate. Coordinates outside the Bulgaria boundary (validated against Natural Earth) are rejected before any charge is applied.
Example use cases
Agricultural land fertility screening
“I'm evaluating a plot near Plovdiv — can you get me the topsoil cation exchange capacity for coordinates 42.15 latitude, 24.75 longitude so I can assess nutrient retention before buying?”
Precision farming soil mapping
“I need the SoilGrids CEC for the 0-5 cm layer at latitude 43.08, longitude 25.62 in Bulgaria to feed into our precision agriculture model.”
Environmental site characterization
“For a reforestation project at 41.9 latitude, 23.4 longitude in Bulgaria, can you pull the mean topsoil CEC so we understand the soil's capacity to hold nutrients?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/bg-soil-cecWhen to prefer
Use this endpoint when you need SoilGrids-derived topsoil cation exchange capacity specifically for a point location in Bulgaria and want a low-cost, per-call microservice with boundary pre-validation. Prefer it over general SoilGrids API access when you need guaranteed Bulgaria-scope filtering and x402 micropayment compatibility.
Side effects
- Coordinate outside Bulgaria boundary — request rejected with a validation error before payment
- Latitude or longitude outside published European coverage range — schema validation failure
- SoilGrids data unavailable for the exact cell — may return null or no-data indicator
- Malformed request body — HTTP 400 bad request
