x402
HALOWERK Atlantic Land – Netherlands Maximum Surface Slope is a paid API for AI agents from atlantikland.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 the analysis grid for a coordinate within the Netherlands boundary.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Netherlands; results outside it are rejected before payment.
Output
A numeric value representing the maximum adjacent-cell first-order surface gradient (steepest slope) across the analysis grid at the given coordinate, constrained to the Netherlands Natural Earth boundary. Coordinates outside the Netherlands boundary are rejected before processing.
Example use cases
Erosion risk site screening
“I'm evaluating a parcel near latitude 51.55, longitude 5.08 in the Netherlands for erosion risk — can you get me the maximum surface slope gradient there so I can see how steep the steepest terrain cell is?”
Construction suitability assessment
“We're scoping a building site at lat 52.10, lon 5.12 in the Netherlands. What's the maximum adjacent-cell slope gradient at that location so we can assess terrain steepness for foundation planning?”
Flood and runoff modeling input
“For a runoff model I'm building, I need the maximum surface slope gradient at coordinates 51.90 latitude, 4.47 longitude within the Netherlands — can you pull that value?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/nl-max-slopeWhen to prefer
Use this endpoint when you need the steepest terrain gradient (maximum adjacent-cell slope) specifically for a coordinate within the Netherlands, as opposed to mean slope or other terrain metrics. It is ideal for erosion risk, construction suitability, and runoff modeling workflows where peak gradient matters more than average slope. The built-in Netherlands boundary validation ensures results are geographically meaningful.
Side effects
- Coordinate outside Netherlands Natural Earth boundary — request rejected before payment
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed request body or missing required coordinate fields — schema validation error
- Payment failure via x402 protocol — transaction not completed
- Temporary service unavailability — HTTP 5xx response
