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 Greece; results outside it are rejected before payment.
Output
A numeric value representing the mean cation exchange capacity (CEC, in cmolc/kg) of the 0–5 cm topsoil layer at the queried coordinate, derived from SoilGrids data. Coordinates outside the Greece boundary are rejected before any result is returned.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a farm plot near Larissa, Greece — can you pull the SoilGrids cation exchange capacity for the 0–5 cm layer at latitude 39.638, longitude 22.419 so I can assess how well the topsoil holds nutrients?”
Vineyard site soil fertility check
“We're scouting vineyard locations in the Peloponnese. Can you get the topsoil CEC from SoilGrids at latitude 37.5, longitude 22.3 so we know how nutrient-retentive the soil is before we invest?”
Environmental research data collection
“I need the cation exchange capacity of the 0–5 cm soil layer at latitude 40.64, longitude 22.94 near Thessaloniki for a soil degradation study — please fetch the SoilGrids CEC value for that coordinate.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/gr-soil-cecWhen to prefer
Use this endpoint when you need a precise, point-level SoilGrids CEC value for the 0–5 cm topsoil layer specifically within Greece, and want built-in boundary validation so out-of-area requests fail cheaply before billing. Prefer it over general soil data APIs when Greece-scoped validation and micro-pricing per call matter.
Side effects
- Coordinate outside Greece boundary: request rejected before payment, no result returned
- Latitude or longitude out of the published European coverage range: validation error
- Missing or malformed latitude/longitude: schema validation failure
- Service unavailable or upstream SoilGrids data issue: server error response
