x402
HALOWERK Nordic Land – DK Soil Coarse-Fragment Volume (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 coarse-fragment volume (volumetric %) for the 0–5 cm soil layer at a given coordinate validated to fall within Denmark.

How this service works
Mean SoilGrids coarse-fragment volume 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
Returns a numeric value representing the mean volumetric coarse-fragment content (% volume) for the 0–5 cm soil layer at the queried coordinate, derived from SoilGrids global soil data. Coordinates outside Denmark's boundary are rejected before any charge is applied.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a parcel of farmland near Viborg — can you check the coarse-fragment volume in the top 5 cm of soil at latitude 56.45, longitude 9.40? I need to know how rocky the topsoil is before I decide on tillage equipment.”
Construction site soil screening
“We're planning a foundation at latitude 55.38, longitude 10.37 in Denmark. Can you pull the SoilGrids coarse-fragment data for the 0–5 cm layer there so our engineers can factor gravel content into the groundwork design?”
Environmental monitoring baseline
“For a wetland restoration project near Esbjerg at latitude 55.47, longitude 8.46, what is the mean coarse-fragment volume in the surface soil layer according to SoilGrids?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/dk-soil-coarse-fragmentsWhen to prefer
Choose this endpoint when you need point-level coarse-fragment volume specifically for a location within Denmark, billed per-call with guaranteed pre-payment boundary validation. Prefer it over general SoilGrids API access when you need a lightweight, metered, boundary-enforced lookup without managing raw SoilGrids credentials. Complements sibling endpoints on the same host for other soil properties (clay, sand, silt, pH, organic carbon) when building a fuller soil profile for a Danish site.
Side effects
- Coordinate falls outside Denmark boundary — request rejected before payment with a geographic validation error
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Payment failure or insufficient USDC balance — x402 payment error returned
- Network timeout or upstream SoilGrids data unavailability — service error response
- Malformed or missing coordinate fields — input validation error
