x402
HALOWERK Baltic Land – Surface Elevation Ruggedness (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 standard deviation of sampled surface elevations for a given coordinate within Germany, quantifying terrain ruggedness.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Germany; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of surface elevations sampled around the queried coordinate within Germany, indicating terrain ruggedness. Higher values indicate more uneven or hilly terrain; lower values indicate flatter terrain. Coordinates outside Germany are rejected before any charge is incurred.
Example use cases
Site suitability for solar farm
“I'm evaluating a potential solar farm site in Germany at latitude 48.8, longitude 11.4 — can you tell me how rugged or flat the terrain is based on elevation standard deviation?”
Hiking trail difficulty assessment
“I want to assess how rough the terrain is along a planned hiking route — start by checking the elevation ruggedness at lat 47.7, lon 12.9 in Bavaria.”
Construction risk screening
“Before we finalize our construction plans, can you check how variable the surface elevation is at latitude 52.1, longitude 13.6 in Germany so we can flag any terrain stability concerns?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/de-ruggednessWhen to prefer
Choose this endpoint when you need a precise, point-based terrain ruggedness metric (elevation standard deviation) specifically for locations within Germany. It is ideal for land suitability analysis, infrastructure planning, environmental modeling, or any workflow that requires knowing how topographically variable a site is. Prefer it over broader European or global DEM APIs when you need Germany-validated results with coordinate boundary enforcement and per-call micropayment pricing.
Side effects
- Coordinate outside Germany boundary: request rejected by Natural Earth validation before payment, returns an error indicating the location is out of coverage
- Latitude or longitude outside the accepted European bounding box (34–72.5°N, -31.5–40.5°E): schema validation failure
- Missing latitude or longitude parameter: request rejected with a validation error
- Network or service unavailability: may return a 5xx error
