HALOWERK Nordic Land – Denmark Maximum Surface Slope
x402
HALOWERK Nordic Land – Denmark Maximum Surface Slope is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the maximum adjacent-cell surface gradient (steepest slope) across an analysis grid for a given coordinate within Denmark.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Denmark; results outside it are rejected before payment.
Output
Returns the maximum adjacent-cell surface slope gradient value across the analysis grid for the queried coordinate. The coordinate is first validated against the Natural Earth boundary for Denmark; requests outside Denmark are rejected before any payment is processed.
Example use cases
Construction site terrain suitability check
“I'm evaluating a site at latitude 56.16, longitude 10.20 in Denmark for a building project — can you tell me the maximum surface slope gradient there so I know if the terrain is too steep?”
Agricultural land drainage planning
“We're planning drainage works on a Danish farm plot near latitude 55.40, longitude 9.75 — what's the maximum slope gradient across the surface there to help us model water runoff?”
Renewable energy site feasibility
“We're scouting a wind turbine installation site at latitude 57.04, longitude 9.92 in Denmark — can you give me the maximum adjacent-cell slope gradient to assess terrain suitability?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/dk-max-slopeWhen to prefer
Use this endpoint when you need the maximum steepness (steepest adjacent-cell slope gradient) specifically for a coordinate within Denmark, rather than mean elevation or standard deviation of elevations. Prefer it over generic elevation APIs when you need terrain ruggedness or slope extremity for use cases like construction feasibility, drainage modeling, or renewable energy site assessment within the Danish boundary.
Side effects
- Coordinate outside Denmark 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 error
- Malformed or missing coordinate parameters — request rejected with input validation error
- Network or service timeout — transient error, retry recommended
