HALOWERK Southern Land – Portugal Terrain Ruggedness (Elevation Std Dev)
x402
HALOWERK Southern Land – Portugal Terrain Ruggedness (Elevation Std Dev) is a paid API for AI agents from suedland.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 WGS84 coordinate in Portugal, quantifying terrain ruggedness at that location.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of sampled surface elevations at the specified coordinate within Portugal. Higher values indicate more rugged, heterogeneous terrain; lower values indicate flat or uniform terrain. Returns an error or rejection if the coordinate falls outside the Natural Earth boundary for Portugal.
Example use cases
Agricultural site suitability in Portugal
“I'm evaluating a plot of land near latitude 39.5, longitude -8.0 in Portugal for farming — can you tell me how rugged or flat the terrain is there based on the elevation standard deviation?”
Renewable energy prospecting
“We're scouting a wind farm location in Portugal at 40.2 latitude, -7.6 longitude — what's the terrain ruggedness score at that point so we can assess installation complexity?”
Hiking trail difficulty assessment
“For a trail planning project, I need the elevation variability at 37.1 latitude, -8.2 longitude in Portugal — give me the standard deviation of surface elevations there.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-ruggednessWhen to prefer
Choose this endpoint when you need a point-specific terrain ruggedness metric for a location in Portugal, particularly for land assessment, agricultural suitability, infrastructure planning, or ecological analysis. It is pre-validated against Portugal's official boundary, reducing the need for client-side geographic filtering. Prefer it over generic elevation APIs when you specifically need variability/ruggedness rather than raw elevation, and when your workflow is scoped to Portuguese territory.
Side effects
- Coordinate outside Portugal's Natural Earth boundary — request rejected before payment is processed
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation error
- Payment failure via x402 protocol — request not fulfilled
