HALOWERK Nordic Land – Iceland Maximum Surface Slope
x402
HALOWERK Nordic Land – Iceland 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 2026-09-15).
Returns the maximum adjacent-cell surface gradient (steepest slope) across the analysis grid for a given coordinate within Iceland.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Iceland; results outside it are rejected before payment.
Output
A numeric value representing the maximum adjacent-cell surface gradient (steepest slope) across the analysis grid centered on the requested coordinate. Coordinates outside the Iceland Natural Earth boundary are rejected before any charge is applied.
Example use cases
Construction site terrain feasibility check
“I'm evaluating a site in Iceland at latitude 65.68, longitude -18.10 — can you get the maximum surface slope there so I can assess whether it's too steep to build on?”
Renewable energy wind farm siting
“We're planning a wind farm in Iceland near latitude 63.98, longitude -22.55. What's the maximum terrain slope at that coordinate so we can evaluate equipment access and foundation requirements?”
Landslide and erosion risk assessment
“For a geohazard study, I need the maximum adjacent-cell surface gradient at latitude 64.50, longitude -19.30 in Iceland — can you pull that slope value for me?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/is-max-slopeWhen to prefer
Choose this endpoint when you specifically need the maximum steepness (steepest adjacent-cell gradient) for a location in Iceland, such as for terrain hazard assessments, construction feasibility, erosion modeling, or renewable energy siting. It is Iceland-specific and validates coordinates against the Natural Earth boundary before charging, making it suitable for automated pipelines. Prefer it over general DEM APIs when you need a pre-computed, pay-per-call max slope value without managing raw elevation rasters.
Side effects
- Coordinate outside Iceland boundary: request 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): validation error
- Malformed or missing coordinate fields: input schema validation error
- Payment failure: x402 payment not completed, request not processed
- Server-side data gap for sparse coverage areas: may return null or error for unmapped grid cells
