HALOWERK Eastern Land – Romania Surface Ruggedness (Elevation Std Dev)
x402
HALOWERK Eastern Land – Romania Surface Ruggedness (Elevation Std Dev) is a paid API for AI agents from ostland.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 WGS84 coordinate validated against Romania's Natural Earth boundary.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Romania; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of sampled surface elevations at the given coordinate, indicating terrain ruggedness. Coordinates outside Romania's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Agricultural suitability screening in Romania
“I'm evaluating farmland plots in Romania — can you check the terrain ruggedness at latitude 44.2, longitude 26.1 so I know how uneven the surface is there?”
Hiking trail difficulty assessment
“I'm planning a trail near latitude 45.5, longitude 25.0 in Romania — how rough is the terrain there based on elevation variability?”
Infrastructure site feasibility check
“We're scoping a construction site in Romania at latitude 46.8, longitude 23.6 — can you pull the surface elevation standard deviation to understand how rugged the terrain is?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/ro-ruggednessWhen to prefer
Choose this endpoint when you need a precise, point-level terrain ruggedness metric (elevation standard deviation) specifically within Romania. It is ideal when you require boundary-validated results and are already working within the HALOWERK Eastern Land ecosystem alongside complementary metrics like slope, aspect, or soil data for the same region.
Side effects
- Coordinate outside Romania's Natural Earth boundary — request rejected with no charge
- Latitude or longitude outside European coverage bounds (34–72.5°N, -31.5–40.5°E) — validation error
- Missing required latitude or longitude fields — schema validation error
- Payment failure via x402 protocol — request not processed
Input
