x402
HALOWERK Land Compare – Local Background Deviation of Depression Depth is a paid API for AI agents from landvergleich.halowerk.com, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-13).
Compares the 60-metre-resolution local depression depth at a given European coordinate against a 1,000-metre local background value from the same source and returns the signed deviation between them.

How this service works
Compares the 60 metre site measurement for local depression depth with a 1,000 metre local background measured from the same source and reports the deviation.
Output
Returns the signed numerical deviation between the 60-metre local depression depth measurement and the 1,000-metre local background depression depth measured at the same source, allowing comparison of micro-scale terrain concavity against its meso-scale context.
Example use cases
Agricultural drainage site assessment
“I'm evaluating a field in the Netherlands near latitude 52.1, longitude 5.4 — can you tell me how much the local depression depth deviates from the surrounding 1km background? I need to understand if water will pool there.”
Urban flood risk pre-screening
“Before we build in this area, check the depression depth deviation at latitude 48.8, longitude 2.3 — I want to know if the 60-metre site reading is significantly lower than the local 1km background, which could indicate flood risk.”
Ecological habitat depression contrast check
“For a conservation project near latitude 47.5, longitude 14.2 in Austria, can you compare the site-level depression depth with the 1km local background and give me the signed deviation?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/local-background-deviation-depression-depthWhen to prefer
Use this endpoint when you need to understand the relative depression depth anomaly of a specific European point compared to its local landscape context — for example, in flood risk screening, agricultural drainage analysis, or ecological site characterisation. Choose it over a simple elevation or slope lookup when the contrast between fine-scale and background-scale depression is the key signal.
Side effects
- Coordinate outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) returns a validation error
- Missing latitude or longitude parameter causes a 400 bad request
- Server unavailability or timeout returns a 5xx error
- Coordinates over ocean or non-covered areas may return null or no-data values
