How this service works
Mean SoilGrids clay fraction 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 SoilGrids clay fraction (as a percentage or volumetric fraction) for the 0–5 cm depth layer at the validated Swedish coordinate. Requests with coordinates outside Sweden's Natural Earth boundary are rejected before payment is processed.
Example use cases
Agricultural soil suitability assessment
“I'm evaluating farmland near Uppsala, Sweden — can you tell me the clay fraction in the top 5 cm of soil at latitude 59.85, longitude 17.63? I want to understand how clay-heavy the soil is before planting.”
Construction site ground characterization
“We're scoping a construction project outside Stockholm at coordinates 59.33 latitude, 18.06 longitude. What's the clay content in the surface soil layer there according to SoilGrids?”
Environmental research data enrichment
“I'm building a dataset of soil properties across Swedish nature reserves. Can you fetch the mean clay fraction for the 0–5 cm layer at latitude 67.85, longitude 20.22 in northern Sweden?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-soil-clayWhen to prefer
Use this endpoint when you need SoilGrids clay fraction data specifically for a point location within Sweden and want built-in boundary validation to avoid erroneous lookups outside the country. Prefer this over generic soil APIs when you need reliable pay-per-call pricing with guaranteed Swedish geographic scoping.
Side effects
- Coordinate outside Sweden boundary — rejected before payment with a boundary validation error
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Network or upstream SoilGrids data unavailability — service error response
- Malformed input (non-numeric coordinates) — input validation error
