HALOWERK Nordic Land – Norway Soil Cation Exchange Capacity (0-5 cm)
x402
HALOWERK Nordic Land – Norway Soil Cation Exchange Capacity (0-5 cm) is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).
Returns the mean SoilGrids cation exchange capacity (CEC) for the 0-5 cm soil layer at a given WGS84 coordinate validated within Norway's boundary.

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 Norway; 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 layer at the requested Norwegian coordinate, sourced from SoilGrids. The coordinate is first validated against Norway's Natural Earth boundary; requests outside Norway are rejected before any charge is made.
Example use cases
Agricultural site suitability assessment
“I'm evaluating a field near Hamar — latitude 60.80, longitude 11.07 — for crop planting. Can you pull the surface soil cation exchange capacity so I know how well it holds nutrients?”
Environmental contamination risk mapping
“We're mapping soil buffering capacity across a remediation site in Norway at coordinates 58.97 latitude, 5.73 longitude. Grab the CEC for the top 5 cm layer from SoilGrids so we can assess how the soil will respond to pollutants.”
Precision forestry soil characterisation
“For a reforestation project at latitude 63.43, longitude 10.39 near Trondheim, I need the mean cation exchange capacity of the surface soil — can you look that up?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/no-soil-cecWhen to prefer
Use this endpoint when you need SoilGrids-sourced surface-layer (0-5 cm) CEC values specifically for locations within Norway, and want pre-validated boundary checking (non-Norwegian coordinates are rejected without charge). Prefer it over generic SoilGrids APIs when operating within a Norway-scoped workflow and when per-call micropayment pricing via x402 is acceptable. It is one of a family of sibling endpoints on the same host covering other soil properties (pH, organic carbon, sand, clay, texture class, etc.) for the same region.
Side effects
- Coordinate outside Norway boundary – request rejected before payment with a boundary validation error
- Coordinate within European coverage range but outside Norway polygon – rejected
- Invalid latitude/longitude values (outside -31.5–40.5 lon or 34–72.5 lat) – schema validation error
- Network timeout or upstream SoilGrids unavailability – service error response
- Payment failure (x402) – call not processed
