HALOWERK Baltic Land – Maximum Surface Slope (Germany)
x402
HALOWERK Baltic Land – Maximum Surface Slope (Germany) is a paid API for AI agents from baltikum.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the maximum adjacent-cell surface gradient across the analysis grid for a given coordinate within Germany.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Germany; results outside it are rejected before payment.
Output
A numeric value representing the maximum adjacent-cell surface gradient (slope) across the analysis grid centered on the queried coordinate within Germany. Coordinates outside the German boundary are rejected before processing.
Example use cases
Construction site slope assessment
“I'm evaluating a potential construction site near Munich at latitude 48.25, longitude 11.60 — can you get me the maximum terrain slope gradient there so I know how steep the land is?”
Erosion risk mapping for farmland
“I need to assess erosion risk for a field at latitude 51.34, longitude 10.22 in central Germany — what's the maximum adjacent-cell surface slope at that location?”
Hiking trail steepness check
“Can you look up the steepest terrain gradient at latitude 47.67, longitude 10.31 in the Allgäu Alps area of Germany? I want to know the maximum slope for trail planning purposes.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/de-max-slopeWhen to prefer
Choose this endpoint when you need a precise maximum adjacent-cell slope gradient specifically for a point location within Germany, particularly for site assessments, erosion analysis, hydrological modeling, or construction planning. It is preferable when Germany-bounded validation is required and you need a single scalar gradient metric rather than a full elevation profile or multi-country dataset.
Side effects
- Coordinate outside Germany boundary — rejected before payment with a validation error
- Latitude or longitude out of the accepted European coverage range (lat 34–72.5, lon -31.5–40.5) — returns a 400-class error
- Malformed or missing input parameters — returns a schema validation error
- Payment failure via x402 protocol — request not fulfilled
