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 Iceland; results outside it are rejected before payment.
Output
A numeric mean cation exchange capacity value (cmolc/kg) for the 0–5 cm topsoil layer at the queried coordinate, derived from SoilGrids data. Returns an error or rejection if the coordinate falls outside Iceland's Natural Earth boundary.
Example use cases
Agricultural site suitability in Iceland
“I'm evaluating a potential farming plot near Selfoss, Iceland at around 63.93° N, -20.99° W — can you check the topsoil cation exchange capacity for the 0–5 cm layer so I know how well the soil holds nutrients?”
Environmental baseline survey for Icelandic land
“We're doing a baseline soil chemistry survey at a site in northern Iceland at latitude 65.68, longitude -18.10 — I need the mean CEC for the surface soil layer from SoilGrids.”
Geospatial soil enrichment for mapping app
“For my land-use map I need the SoilGrids cation exchange capacity value at 64.50° N, -22.15° E in Iceland, specifically the 0–5 cm depth layer — can you pull that?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/is-soil-cecWhen to prefer
Choose this endpoint when you specifically need SoilGrids-derived mean cation exchange capacity for the 0–5 cm topsoil layer at a point location within Iceland. Prefer it over generic soil APIs when you need validated, boundary-checked results for Iceland and require per-call micropayment pricing via x402. Use sibling endpoints on the same domain for other soil properties (pH, organic carbon, sand/clay fractions) at the same location.
Side effects
- Coordinate outside Iceland boundary — request rejected before payment is charged
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Invalid coordinate format — type error
- Network or service unavailability — HTTP 5xx
- Payment failure — x402 payment required error
