x402
HALOWERK Europe Land – Terrain Ruggedness Point (60m Grid) is a paid API for AI agents from euroland.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 within a 60-metre local analysis grid around a single WGS84 coordinate in Europe, as a measure of terrain ruggedness.

How this service works
Standard deviation of sampled surface elevations. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.
Output
A single numeric value representing the standard deviation of surface elevations sampled within a 60-metre local analysis grid around the submitted coordinate, expressed in standardized units. This quantifies terrain ruggedness — higher values indicate more uneven, hilly, or mountainous terrain; lower values indicate flat or uniform surfaces.
Example use cases
Site suitability for renewable energy
“I'm evaluating a potential wind farm site in southern Spain at latitude 37.8, longitude -5.2 — can you check the terrain ruggedness score there so I know how uneven the ground is?”
Hiking trail difficulty assessment
“We're planning a hiking route through the Alps and need to know how rugged the terrain is at latitude 47.1, longitude 10.9 — can you get the elevation standard deviation for that point?”
Agricultural land flatness check
“I need to assess whether the land at latitude 51.3, longitude 12.4 in Germany is flat enough for large-scale mechanized farming — what's the terrain ruggedness score for that coordinate?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-ruggedness-pointWhen to prefer
Choose this endpoint when you need a fast, single-point terrain ruggedness metric for any of the 30 covered European countries, specifically as an elevation standard deviation over a 60-metre local grid. It is ideal for lightweight point queries without polygon or radius inputs, and is distinct from the 250m or 1,000m circular-radius sibling endpoints. Prefer this over broader geospatial APIs when you need Europe-specific, standardized ruggedness scores with per-call pricing.
Side effects
- Coordinate outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) returns an error or empty result
- Invalid or non-numeric latitude/longitude values cause a validation error
- Coastal or water-body coordinates may return low-confidence or null elevation data
- Payment failure or insufficient USDC balance (x402 protocol) blocks the request
- Server timeout or upstream DEM data unavailability returns a 5xx error
