How this service works
Mean SoilGrids clay fraction 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 value representing the mean clay fraction (as a percentage or volumetric fraction) in the 0-5 cm topsoil layer at the requested coordinate, sourced from SoilGrids. Requests with coordinates outside Iceland's Natural Earth boundary are rejected before billing.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a potential farming site in Iceland at coordinates 65.2°N, -18.6°E — can you look up the mean clay fraction in the topsoil (0-5 cm) there so I can assess drainage and tillage suitability?”
Environmental baseline survey
“For my environmental impact report, I need the SoilGrids clay content for the top 5 cm of soil at lat 63.8, lon -22.1 in Iceland — can you pull that for me?”
Geospatial soil data enrichment pipeline
“I'm building a soil property dataset for Iceland and need the mean clay fraction at the 0-5 cm depth for the coordinate at 66.05 latitude, -18.75 longitude — can you fetch that value?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/is-soil-clayWhen to prefer
Use this endpoint when you need topsoil clay fraction data specifically for Iceland and want a pay-per-call, boundary-validated lookup without managing a full SoilGrids API integration. Prefer it over raw SoilGrids when Iceland-specific coordinate gating and per-query micropayment billing are desired. For other soil properties (sand, pH, organic carbon) or other Nordic countries, use the sibling endpoints on the same provider.
Side effects
- Coordinate outside Iceland Natural Earth boundary — request rejected with a boundary validation error, no charge
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Invalid or missing coordinate fields — 400-level error
- SoilGrids data unavailable for the exact cell — possible null or no-data response
