HALOWERK Atlantic Land – Netherlands Depression Depth
x402
HALOWERK Atlantic Land – Netherlands Depression Depth is a paid API for AI agents from atlantikland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the positive difference between a neighborhood mean elevation and the center point elevation, indicating topographic depression depth for a coordinate in the Netherlands.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Netherlands; results outside it are rejected before payment.
Output
A numeric value representing the positive elevation difference (in metres) between the neighborhood mean elevation and the center point elevation at the given coordinate, indicating how much of a topographic depression exists at that location. Coordinates outside the Netherlands boundary are rejected before processing.
Example use cases
Flood risk site screening in the Netherlands
“I'm evaluating a site in Amsterdam at 52.3702 latitude and 4.8952 longitude — can you tell me the depression depth there so I know how much lower it sits than its surrounding terrain?”
Dutch agricultural land drainage assessment
“We're planning drainage works on farmland near Groningen at lat 53.2194, lon 6.5665 — what's the topographic depression depth at that point so we can estimate runoff accumulation risk?”
Urban infrastructure siting in low-lying areas
“Before we approve this building permit near Rotterdam at latitude 51.9225 and longitude 4.4792, can you check the depression depth to see if the plot sits in a topographic sink?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/nl-depression-depthWhen to prefer
Choose this endpoint when you need a precise, point-level topographic depression depth metric specifically for Netherlands coordinates, particularly for flood risk assessment, drainage planning, or land suitability analysis. It is ideal for agents that need a validated, boundary-checked elevation sink metric rather than raw DEM data. Prefer this over generic elevation APIs when the Netherlands boundary validation and neighborhood-relative depression computation are required.
Side effects
- Coordinate outside Netherlands Natural Earth boundary — request rejected before payment
- Latitude or longitude out of European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Invalid or missing coordinate fields — schema validation failure
- No depression present (flat or elevated point) — may return zero or near-zero value
- Service unavailable or payment processing error — HTTP 402 or 5xx response
