HALOWERK Nordic Land — Denmark Depression Depth
x402
HALOWERK Nordic Land — Denmark Depression Depth is a paid API for AI agents from nordland.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, quantifying topographic depression depth at a given coordinate in Denmark.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Denmark; results outside it are rejected before payment.
Output
A numeric value representing the positive elevation difference (in meters) between the neighborhood mean surface elevation and the center cell elevation, indicating how much of a topographic depression exists at the queried point. Coordinates outside Denmark's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Flood risk assessment for Danish site
“I need to know how deep the topographic depression is at latitude 56.15, longitude 10.21 in Denmark — we're assessing whether this location is prone to water pooling.”
Agricultural drainage planning
“Can you calculate the depression depth at coordinates 55.45 latitude, 9.87 longitude in Denmark? We're planning drainage works and need to know how much the land dips below its surroundings.”
Environmental impact site survey
“For our environmental survey at 57.04 north latitude and 9.93 east longitude in Denmark, what is the depression depth value — the difference between the neighborhood mean elevation and the center point elevation?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/dk-depression-depthWhen to prefer
Choose this endpoint when you need a precise, per-point topographic depression depth metric specifically for locations within Denmark, particularly for hydrology, flood-risk, drainage, or land-use applications. It is preferable over general elevation APIs because it computes the neighborhood-mean-minus-center-elevation metric directly, saving local raster processing. The pre-payment boundary validation means you won't be charged for out-of-scope coordinates.
Side effects
- Coordinate outside Denmark's Natural Earth boundary — request rejected before payment, no result returned
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate parameters — input schema validation failure
- Point within European bounds but outside Denmark polygon — boundary rejection
- Service unavailability or timeout — HTTP 5xx error
