x402
HALOWERK Europe Land – Depression Depth Buffer 1000m is a paid API for AI agents from euroland.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-15).
Returns the positive elevation difference between the 1,000-metre circular neighborhood mean and the center point elevation, measuring how much lower a location sits relative to its surroundings across 30 European countries.

How this service works
Positive difference between the neighborhood mean and center elevation. The service evaluates a circular 1,000 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A numeric value representing the positive difference (in standardized units) between the mean elevation of the 1,000-metre circular neighborhood and the elevation at the center coordinate — indicating how much lower the queried point sits relative to its surroundings. A higher value indicates a deeper terrain depression or sink.
Example use cases
Flood risk site screening
“Can you check how topographically depressed the area is around latitude 51.5074, longitude -0.1278 using a 1km neighborhood? I want to understand if this site sits in a natural low point that could collect water.”
Real estate terrain assessment
“I'm evaluating a parcel at latitude 47.3769, longitude 8.5417 in Switzerland — can you tell me the depression depth index for a 1km radius so I know if the land sits in a hollow relative to its surroundings?”
Infrastructure planning elevation analysis
“For a proposed road segment centered at latitude 52.2297, longitude 21.0122 in Poland, what is the 1,000-metre depression depth? I need to know how much lower the center sits versus the neighborhood mean elevation.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-depression-depth-buffer-1000mWhen to prefer
Use this endpoint when you need a terrain depression metric for a specific European coordinate using a 1,000-metre neighborhood radius. It is ideal for flood risk screening, land suitability analysis, infrastructure planning, or any application needing to quantify how much a point sits below its local surroundings. Prefer this over the 60m or 250m radius variants when broader neighborhood context (1km) is needed to smooth local terrain noise.
Side effects
- Coordinates outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) return an error or null result
- Coordinates in ocean or non-land areas may return no meaningful elevation delta
- Payment failure via x402 protocol prevents response
- Malformed or missing latitude/longitude parameters cause a 4xx validation error
