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 Sweden; results outside it are rejected before payment.
Output
A numeric value representing the mean cation exchange capacity (CEC) in cmolc/kg for the 0–5 cm topsoil layer at the queried coordinate, sourced from SoilGrids. Coordinates outside Sweden's Natural Earth boundary are rejected before any charge is incurred.
Example use cases
Agricultural soil fertility assessment
“I'm evaluating a field near Uppsala — latitude 59.86, longitude 17.64. Can you pull the SoilGrids cation exchange capacity for the top 5 cm of soil there so I can assess how well it holds nutrients?”
Environmental impact site screening
“We're doing a pre-construction soil assessment for a site at lat 57.70, lon 11.97 in Gothenburg. Can you get the CEC reading for the 0–5 cm layer from SoilGrids so we have a baseline fertility indicator?”
Precision agriculture variable-rate planning
“I'm building a soil map for a precision farming project in Skåne. Can you look up the cation exchange capacity at latitude 55.60, longitude 13.00 so I can calibrate fertiliser application rates for that zone?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-soil-cecWhen to prefer
Choose this endpoint when you need a fast, pay-per-call SoilGrids CEC topsoil reading validated specifically for Sweden, without building your own SoilGrids pipeline. It is ideal for agents enriching agricultural, ecological, or land-use datasets with soil fertility indicators at point locations inside Sweden. Prefer it over raw SoilGrids API access when boundary validation, micropayment billing, and a simple POST interface are desirable.
Side effects
- Coordinate outside Sweden boundary – request rejected, no charge applied
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) – validation error
- Missing required latitude or longitude field – schema validation error
- SoilGrids data unavailable for the queried cell – may return null or error response
- Network timeout or upstream SoilGrids service outage – 5xx error
Input
