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 Estonia; results outside it are rejected before payment.
Output
A numeric value representing the mean cation exchange capacity (CEC) of the 0-5 cm topsoil layer derived from SoilGrids, expressed in cmolc/kg, for the requested Estonian coordinate. Coordinates outside Estonia's boundary are rejected before any charge is incurred.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a farm plot in Estonia near coordinates 58.95 latitude, 25.55 longitude — can you pull the topsoil cation exchange capacity so I can judge its nutrient-holding ability?”
Environmental baseline for construction project
“We're preparing an environmental impact report for a site in Tallinn, Estonia at 59.4370 latitude, 24.7536 longitude — fetch the mean SoilGrids CEC for the top 5 centimetres of soil there.”
Soil carbon and fertility mapping workflow
“I'm building a soil fertility map for Estonian parcels — start by getting the cation exchange capacity of the 0-5 cm layer for the point at latitude 57.8750, longitude 27.0200.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/ee-soil-cecWhen to prefer
Choose this endpoint when you specifically need SoilGrids-derived topsoil CEC data for a point known to be within Estonia, and you want boundary validation enforced server-side before payment. It is preferable over general SoilGrids APIs when you need a pay-per-call microservice with built-in Estonian geographic validation and no API key management.
Side effects
- Coordinate outside Estonia boundary: request rejected before payment with a boundary-validation error
- Coordinate within Europe but outside Estonian polygon: rejected despite being within the input schema's broader European bounding box
- Latitude or longitude outside the declared European range (34–72.5°N, -31.5–40.5°E): schema validation error
- Network or upstream SoilGrids data unavailability: service error response
- Malformed JSON body or missing required fields: 400-level error
