x402
HALOWERK Central Land – Slovakia Terrain Ruggedness (Standard Deviation of Elevation) 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 standard deviation of sampled surface elevations within a neighborhood around a given coordinate in Slovakia, quantifying terrain ruggedness.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Slovakia; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of sampled surface elevations within a neighborhood around the requested coordinate in Slovakia. Higher values indicate more rugged, uneven terrain; lower values indicate flatter terrain. The coordinate is validated against Slovakia's Natural Earth boundary before processing.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a plot in Slovakia near latitude 48.6, longitude 18.1 — can you get me the elevation standard deviation there so I know how rugged the terrain is for farming?”
Hiking trail difficulty classification
“I'm building a trail difficulty map for Slovakia. Can you compute the elevation standard deviation at latitude 49.1, longitude 20.2 to help classify how rugged that section of terrain is?”
Infrastructure site selection in Slovakia
“We're scouting a construction site in Slovakia at approximately latitude 48.3, longitude 17.5 — can you check how rugged the terrain is by getting the standard deviation of elevations there?”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/sk-ruggednessWhen to prefer
Choose this endpoint when you need a quantitative measure of terrain roughness or variability specifically within Slovakia, based on Copernicus DEM GLO-30 elevation data. It is ideal for applications requiring ruggedness indices such as agricultural suitability, infrastructure planning, ecological modeling, or trail characterization. Prefer it over mean elevation endpoints when elevation variability—not absolute height—is what matters.
Side effects
- Coordinate outside Slovakia's Natural Earth boundary returns a rejection error before computation
- Latitude or longitude outside allowed European coverage range (34–72.5°N, -31.5–40.5°E) returns a validation error
- Payment failure via x402 protocol results in no data returned
- Missing latitude or longitude fields cause a request validation error
