x402
HALOWERK Baltic Land – Estonia Terrain Ruggedness (Surface Elevation Std Dev) 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 at a given coordinate within Estonia, quantifying terrain ruggedness.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Estonia; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of sampled surface elevations at the queried coordinate, indicating the degree of terrain ruggedness. Coordinates outside Estonia's Natural Earth boundary are rejected before payment is processed.
Example use cases
Site suitability for wind farm
“I'm evaluating a potential wind farm location in Estonia at 59.1°N, 24.8°E — can you get me the terrain ruggedness score (surface elevation standard deviation) for that spot so I know how flat or hilly the terrain is?”
Hiking trail difficulty assessment
“I'm planning a hiking route and want to know how rough the terrain is near latitude 57.85, longitude 27.02 in Estonia — what's the standard deviation of surface elevations there?”
Agricultural land flatness check
“I need to assess how rugged the land is at a farm plot in Estonia located at 58.4°N, 25.6°E — can you look up the surface elevation standard deviation for that coordinate?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/ee-ruggednessWhen to prefer
Choose this endpoint when you need a quantitative measure of terrain roughness or topographic variability (standard deviation of elevations) at a specific point in Estonia. It is ideal for site suitability analysis, infrastructure planning, environmental modeling, or any task requiring a nuanced elevation variability metric rather than just max/min range. For elevation range instead of spread, use the sibling endpoint returning the difference between max and min elevation. For slope or runoff tendency, use the dedicated gradient or runoff siblings.
Side effects
- Coordinate outside Estonia boundary — request rejected without charge
- Latitude or longitude out of European coverage range — validation error
- Malformed coordinate values — input schema validation failure
- Service unavailability — HTTP 5xx error
