HALOWERK Baltic Land – Latvia Terrain Ruggedness (Surface Elevation Std Dev)
x402
HALOWERK Baltic Land – Latvia 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 (terrain ruggedness index) for a given WGS84 coordinate within Latvia.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Latvia; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of surface elevations sampled around the queried coordinate within Latvia, indicating terrain ruggedness. Coordinates outside Latvia's boundary as defined by the Natural Earth dataset are rejected before any charge is incurred.
Example use cases
Site suitability for infrastructure in Latvia
“I'm evaluating a site near Cēsis, Latvia — latitude 57.31, longitude 25.27 — can you tell me how rugged or uneven the terrain is there based on surface elevation variation?”
Agricultural land flatness assessment
“I need to check how flat the terrain is for a potential field at latitude 56.50, longitude 21.01 in Latvia — what's the standard deviation of surface elevations at that point?”
Flood risk terrain profiling
“For our environmental report, can you get the terrain ruggedness value — elevation standard deviation — at latitude 56.65, longitude 23.72 in Latvia?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/lv-ruggednessWhen to prefer
Use this endpoint when you need a quantitative terrain ruggedness metric (surface elevation standard deviation) specifically for a point within Latvia. It is ideal for geospatial analysis pipelines covering Latvian land surface characteristics, infrastructure siting, agricultural assessment, or environmental modeling where boundary validation against Natural Earth Latvia geometry is required before billing.
Side effects
- Coordinate outside Latvia's Natural Earth boundary — request rejected, no charge
- Latitude or longitude outside 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 or insufficient USDC balance — transaction not processed
Input
