HALOWERK Nordic Land – Finland Terrain Ruggedness Index
x402
HALOWERK Nordic Land – Finland Terrain Ruggedness Index is a paid API for AI agents from nordland.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 (terrain ruggedness) for a given coordinate within Finland.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Finland; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of sampled surface elevations at the queried coordinate — quantifying terrain ruggedness. Higher values indicate more variable, hilly, or rough terrain; lower values indicate flatter land. Coordinates outside Finland's Natural Earth boundary are rejected before any payment is charged.
Example use cases
Site suitability for wind farm
“I'm evaluating a potential wind farm site in Finland — can you get the terrain ruggedness index for latitude 66.1, longitude 26.4? I need to know how variable the surface elevations are there.”
Hiking trail difficulty assessment
“I'm planning a hiking route and want to know how rugged the terrain is near latitude 68.9, longitude 27.1 in Finland — can you pull the elevation standard deviation for that location?”
Infrastructure routing risk analysis
“We're assessing road construction risk in Finland. Can you check the terrain ruggedness at coordinates latitude 62.5, longitude 29.8 to understand how irregular the surface elevations are?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/fi-ruggednessWhen to prefer
Use this endpoint when you need terrain ruggedness specifically for Finnish coordinates, as it enforces Finland boundary validation before charging and provides a focused, cost-efficient single-call computation. Prefer this over generic elevation APIs when you need standard deviation of sampled elevations (not just point elevation) and are working within Finland.
Side effects
- Coordinate outside Finland's Natural Earth boundary — request rejected before payment
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing required latitude or longitude parameters — schema validation failure
- Payment failure via x402 protocol — request not processed
