HALOWERK Southern Land – Spain Terrain Ruggedness Index
x402
HALOWERK Southern Land – Spain Terrain Ruggedness Index 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).
Computes the standard deviation of sampled surface elevations (terrain ruggedness) for a given WGS84 coordinate within Spain, validated against Natural Earth boundaries.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Spain; results outside it are rejected before payment.
Output
Returns a numeric value representing the standard deviation of sampled surface elevations at the requested coordinate, indicating how rugged or variable the terrain is. Coordinates outside the Natural Earth boundary for Spain are rejected before processing or payment is charged.
Example use cases
Site suitability for solar farm
“Can you check how rugged the terrain is at latitude 37.88, longitude -4.77 in Spain? I need the elevation standard deviation to assess whether the land is flat enough for a solar installation.”
Hiking trail difficulty assessment
“I'm planning a trail near latitude 42.65, longitude -0.55 in the Pyrenees — what's the terrain ruggedness score there so I can estimate how challenging the route will be?”
Agricultural land flatness screening
“Run a terrain ruggedness check for coordinates 39.47 latitude, -0.38 longitude in Valencia, Spain — I need to know how variable the surface elevation is before we consider it for large-scale crop farming.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-ruggednessWhen to prefer
Choose this endpoint when you need a quantitative measure of terrain roughness or surface elevation variability for a specific point in Spain, especially for applications like land suitability analysis, infrastructure planning, agricultural screening, or ecological modeling. It is preferred over generic elevation lookup endpoints because it returns a statistical variability metric (standard deviation) rather than a single elevation value, and it strictly validates inputs against Spain's boundary before charging.
Side effects
- Coordinate outside Spain boundary — request rejected before payment with a validation error
- Latitude or longitude out of published European coverage range (34–72.5°N, -31.5–40.5°E) — schema validation failure
- Malformed or missing latitude/longitude fields — input validation error
- Service unavailable or upstream elevation data temporarily inaccessible — HTTP 5xx error
