HALOWERK Central Land – Austria Maximum Surface Slope
x402
HALOWERK Central Land – Austria Maximum Surface Slope is a paid API for AI agents from mitteleuropa.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 an analysis grid for a given coordinate within Austria, derived from terrain elevation data.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Austria; results outside it are rejected before payment.
Output
A numerical value representing the maximum adjacent-cell surface gradient (slope) across the analysis grid centered on the queried coordinate within Austria. Coordinates outside the Austrian Natural Earth boundary are rejected before the payment is processed.
Example use cases
Alpine site suitability assessment
“I'm evaluating a site near latitude 47.1, longitude 12.8 in Austria for construction — can you get the maximum terrain slope at that coordinate so I can assess slope risk?”
Ski run steepness check
“What's the maximum slope gradient at latitude 47.5, longitude 12.95 in Austria? I want to see how steep the terrain is for a potential ski route.”
Erosion risk screening
“For a land parcel at latitude 48.1, longitude 14.3 in Austria, calculate the maximum adjacent-cell surface slope so I can evaluate erosion risk for the agricultural report.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/at-max-slopeWhen to prefer
Use this endpoint when you need the maximum (peak) surface slope value at a specific point within Austria, as opposed to mean slope or elevation. It is ideal for steepness-focused analyses such as construction suitability, erosion risk, or terrain hazard assessment. Prefer it over mean-slope sibling endpoints when the worst-case gradient matters more than the average.
Side effects
- Coordinate outside Austria's Natural Earth boundary — rejected before payment with a validation error
- Latitude or longitude outside the European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed or missing latitude/longitude parameters — request rejected with input error
- Service unavailable or upstream DEM data error — may return a 5xx error
