HALOWERK Nordic Land — Denmark Soil Silt Fraction (0-5 cm)
x402
HALOWERK Nordic Land — Denmark Soil Silt Fraction (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 silt fraction for the 0-5 cm depth layer at a given WGS84 coordinate validated to be within Denmark's boundary.

How this service works
Mean SoilGrids silt fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Denmark; results outside it are rejected before payment.
Output
A numeric value representing the mean silt fraction (likely as a percentage or g/kg proportion) for the 0-5 cm soil depth at the queried coordinate, sourced from SoilGrids. Returns an error or rejection if the coordinate falls outside Denmark's Natural Earth boundary.
Example use cases
Agricultural soil texture assessment
“I'm planning a crop rotation on a field near Odense — can you look up the silt fraction in the top 5 cm of soil at latitude 55.396 and longitude 10.388?”
Environmental contamination site screening
“We're doing a soil risk assessment at a remediation site near Aalborg at lat 57.048, lon 9.921 in Denmark — pull the topsoil silt fraction from SoilGrids for that coordinate.”
Construction foundation soil characterization
“Before we finalize the foundation design for a building plot at latitude 55.863, longitude 9.842 in Denmark, can you fetch the mean silt content for the 0-5 cm soil layer there?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/dk-soil-siltWhen to prefer
Choose this endpoint when you specifically need the SoilGrids silt fraction for the 0-5 cm topsoil layer at a point coordinate within Denmark. It is ideal for soil texture analysis pipelines alongside companion endpoints for sand, clay, pH, and organic carbon. Prefer it over generic soil APIs when Denmark-specific boundary validation and per-call micropayment (x402) pricing are acceptable constraints.
Side effects
- Coordinate outside Denmark boundary — rejected before payment is processed
- Latitude or longitude out of accepted European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Coordinate within Europe but outside Denmark — rejected by boundary check
- Malformed or missing latitude/longitude fields — input validation error
- SoilGrids data unavailable for the requested location — possible null or error response
