x402
HALOWERK Baltic Land – Terrain Ruggedness Standard Deviation (Poland) 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 for a given coordinate within Poland, quantifying local terrain ruggedness.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Poland; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of sampled surface elevation values within the analysis grid around the given coordinate. Higher values indicate more rugged, heterogeneous terrain; the coordinate is first validated to fall within Poland's Natural Earth boundary before the computation is returned.
Example use cases
Construction site terrain assessment
“Can you get the elevation standard deviation for the site at latitude 52.23, longitude 21.01 in Poland? I need to know how rugged the terrain is before we plan the groundwork.”
Wind farm suitability screening
“What's the terrain ruggedness at latitude 54.35, longitude 18.65 in Poland — I need the elevation variability to check whether the surface is smooth enough for turbine placement.”
Flood risk terrain profiling
“Get me the surface elevation standard deviation for latitude 51.1, longitude 17.03 in Poland — I'm trying to understand how uneven the terrain is around that catchment area.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-ruggednessWhen to prefer
Choose this endpoint when you need a statistical measure of terrain heterogeneity (standard deviation of elevation samples) specifically for locations within Poland. It is distinct from range-based ruggedness (max–min elevation difference) and slope-gradient metrics available on the same platform. Prefer this for applications where variance-based roughness is needed, such as ecological modeling, infrastructure siting, or hydrological analysis within Poland.
Side effects
- Coordinate outside Poland boundary: request is rejected before processing (validation failure, no charge)
- Coordinate outside overall European coverage range: rejected by input schema validation
- Missing latitude or longitude parameters: request fails with validation error
- Network or service unavailability: HTTP 5xx or timeout
- Payment failure via x402 protocol: request not processed
