x402
HALOWERK Central Land – Terrain Ruggedness Index (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).
Computes the standard deviation of sampled surface elevations around a given coordinate within Liechtenstein, quantifying local terrain ruggedness.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Liechtenstein; results outside it are rejected before payment.
Output
Returns the standard deviation of surface elevations sampled within the analysis neighborhood around the given coordinate, expressed as a numeric ruggedness metric. Coordinates outside the Liechtenstein boundary are rejected before processing.
Example use cases
Site suitability for construction in Liechtenstein
“Can you check how rugged the terrain is at coordinates 47.16 latitude, 9.55 longitude in Liechtenstein? I need the elevation standard deviation to assess whether it's suitable for building.”
Agricultural land roughness assessment
“I'm evaluating farmland near Vaduz — can you get me the terrain ruggedness index at 47.13 latitude, 9.51 longitude so I can judge how variable the surface elevation is there?”
Hiking trail difficulty classification
“For a trail planning project, can you calculate the surface elevation variability at 47.20 latitude, 9.58 longitude in Liechtenstein to help classify terrain difficulty in that area?”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/li-ruggednessWhen to prefer
Choose this endpoint when you need a precise terrain ruggedness metric (elevation standard deviation) for a specific point within Liechtenstein, backed by Copernicus DEM GLO-30 data and with built-in boundary validation. Prefer it over generic elevation APIs when ruggedness (not just raw elevation) is the required output and the location is confirmed to be within Liechtenstein.
Side effects
- Coordinate outside Liechtenstein boundary: request rejected before payment is charged
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5): validation error
- Invalid or missing coordinate fields: schema validation failure
- Payment not settled via x402 protocol: request not processed
