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 Hungary; results outside it are rejected before payment.
Output
A numeric mean cation exchange capacity (CEC) value in cmolc/kg for the 0–5 cm soil depth at the queried coordinate, derived from the SoilGrids dataset. Coordinates outside Hungary's Natural Earth boundary are rejected without a result.
Example use cases
Precision agriculture soil assessment
“I'm evaluating a field in Hungary near Budapest — latitude 47.52, longitude 18.93 — can you pull the mean CEC for the top 5 centimetres of soil so I can assess nutrient-holding capacity?”
Land suitability scoring for viticulture
“I'm comparing vineyard sites in Hungary. Can you get me the topsoil cation exchange capacity at 46.88 latitude, 17.65 longitude to factor into my soil quality score?”
Environmental monitoring data enrichment
“I'm building a dataset of soil properties across Hungarian nature reserves. Fetch the SoilGrids CEC value for the 0–5 cm layer at coordinates 47.1 latitude, 20.3 longitude.”

Endpoint
POSThttps://ostland.halowerk.com/v1/hu-soil-cecWhen to prefer
Choose this endpoint when you specifically need SoilGrids-derived CEC data for the 0–5 cm topsoil layer at a point within Hungary. It is distinct from generic European coverage endpoints because it applies Hungary-specific boundary validation, making it reliable for Hungarian land assessment workflows. Prefer it over raw SoilGrids API access when you want a simple, paid-per-call interface without managing API keys.
Side effects
- Coordinate outside Hungary boundary — request rejected before processing
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation failure
- Payment failure via x402 — call not processed
- Upstream SoilGrids data unavailable for very remote or uncovered cells
Input
