HALOWERK Central Land – Maximum Surface Slope (Liechtenstein)
x402
HALOWERK Central Land – Maximum Surface Slope (Liechtenstein) is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the maximum adjacent-cell surface gradient across a local analysis grid for a coordinate within Liechtenstein, derived from Copernicus DEM GLO-30 data.

How this service works
Maximum adjacent-cell surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Liechtenstein; results outside it are rejected before payment.
Output
A numerical value representing the maximum adjacent-cell surface gradient (steepest slope) across the local analysis grid at the queried coordinate, expressed as a gradient measure. Coordinates outside the Liechtenstein boundary are rejected before processing.
Example use cases
Landslide risk screening for a site
“I'm assessing landslide risk for a construction site in Liechtenstein at 47.12° N, 9.53° E — can you pull the maximum surface gradient there so I know how steep the terrain is?”
Hiking trail steepness assessment
“We're planning a trail near 47.16° N, 9.55° E in Liechtenstein — what's the maximum slope of the terrain at that coordinate?”
Agricultural suitability check
“I need to know if land at 47.10° N, 9.51° E in Liechtenstein is too steep for crop farming — what's the maximum surface gradient there?”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/li-max-slopeWhen to prefer
Use this endpoint when you need the maximum adjacent-cell surface slope for a specific point within Liechtenstein, as opposed to mean slope or slope direction. It is ideal for terrain steepness analysis, risk assessment, and land suitability workflows scoped specifically to Liechtenstein. Prefer this over general DEM APIs when boundary validation against Liechtenstein is required.
Side effects
- Coordinate outside Liechtenstein boundary — rejected with an error before payment
- Latitude or longitude out of valid European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed or missing coordinate fields — request rejected
- Network timeout or service unavailability — no result returned
