HALOWERK Baltic Land – Depression Depth
x402
HALOWERK Baltic Land – Depression Depth 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 positive elevation difference between a neighborhood mean and the center cell elevation, indicating topographic depression depth at a given coordinate in Germany.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Germany; results outside it are rejected before payment.
Output
A numeric value representing the positive elevation difference (in meters) between the mean elevation of the surrounding neighborhood cells and the center cell elevation, indicating how deep a topographic depression is at the queried point. Returns an error if the coordinate falls outside the validated Germany boundary.
Example use cases
Flood risk site screening
“Can you check the depression depth at latitude 52.12, longitude 13.45 in Germany? I need to know how much lower that point is than the surrounding terrain to assess local flood pooling risk.”
Agricultural drainage planning
“I'm evaluating a field in Germany at lat 51.8, lon 10.2 — what's the depression depth there? I need to know if water is likely to collect at that spot.”
Infrastructure site suitability check
“Before we finalize this construction site in Germany at coordinates 53.6 latitude, 9.9 longitude, can you pull the depression depth so we know if the center sits in a topographic low relative to its surroundings?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/de-depression-depthWhen to prefer
Choose this endpoint when you need a precise, point-level measure of topographic depression depth (neighborhood mean minus center elevation) for a specific coordinate within Germany. It is ideal for hydrology, flood risk, drainage analysis, and terrain characterization workflows where understanding local surface lows matters. It differs from general elevation lookup (which returns absolute height) or slope/gradient endpoints (which measure steepness rather than sinks).
Side effects
- Coordinate outside Germany boundary returns a rejection error before payment is processed
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) is rejected at input validation
- Invalid or missing coordinate fields return a schema validation error
- Ambiguous coordinates on the boundary may be rejected due to strict Natural Earth polygon matching
