HALOWERK Europe Land – Depression Depth (Point)
x402
HALOWERK Europe Land – Depression Depth (Point) 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 positive difference between the neighborhood mean elevation and the center point elevation, quantifying how deep a topographic depression is at a given European coordinate.

How this service works
Positive difference between the neighborhood mean and center elevation. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.
Output
A standardized numeric value representing the positive elevation difference between the 60-metre neighbourhood mean elevation and the center point elevation (depression depth in consistent units), covering any coordinate within the 30-country European coverage area.
Example use cases
Flood risk site screening
“I'm evaluating a construction site near Warsaw at 52.23 latitude, 21.01 longitude — can you tell me the depression depth there so I know whether surface water might pool at that location?”
Agricultural drainage planning
“We're planning drainage works on a field in the Netherlands at 52.10 latitude, 5.12 longitude. Can you check the depression depth using the 60-metre neighbourhood analysis to see if it's a significant topographic sink?”
Ecological habitat mapping
“For a wetland restoration project in France at 47.80 latitude, 2.35 longitude, I need the local depression depth metric — how deep is that point relative to its surrounding terrain?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-depression-depth-pointWhen to prefer
Choose this endpoint when you need a fast, standardized depression-depth metric for a single European point using a fixed 60-metre local analysis window, especially when comparing terrain concavity consistently across multiple countries. It is purpose-built for European land coverage and returns a ready-to-use numeric metric without requiring you to source or process elevation rasters yourself.
Side effects
- Coordinates outside the European coverage bounds (latitude 34–72.5°N, longitude −31.5–40.5°E) return a validation error
- Coordinates over open ocean or outside land coverage may return null or no-data values
- Invalid or non-numeric coordinate inputs cause a schema validation error
- Payment failure or insufficient USDC balance results in a 402 Payment Required response
