HALOWERK Nordic Land – SE Depression Depth
x402
HALOWERK Nordic Land – SE 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 depth of a topographic depression at a given coordinate in Sweden, computed as the difference between the neighborhood mean elevation and the center-point elevation.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Sweden; results outside it are rejected before payment.
Output
A numeric value representing the depression depth in meters — the positive difference between the neighborhood mean surface elevation and the center-point elevation at the queried coordinate. Coordinates outside Sweden's Natural Earth boundary are rejected before any charge is incurred.
Example use cases
Flood risk site screening
“I'm assessing potential flood risk zones for a construction project in Sweden. Can you check the depression depth at latitude 57.70, longitude 11.97? I need to know how much lower that point is than the surrounding terrain.”
Wetland habitat mapping
“I'm mapping potential wetland habitats in Sweden and need to know if this coordinate — latitude 63.18, longitude 17.32 — sits in a topographic depression and how deep it is.”
Agricultural drainage planning
“We're planning drainage improvements on farmland in Sweden. Can you calculate the depression depth at latitude 55.60, longitude 13.00 so we know how much the terrain sinks relative to its surroundings?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-depression-depthWhen to prefer
Use this endpoint when you need a precise, pay-per-call terrain depression metric for a specific point in Sweden without setting up your own DEM processing pipeline. It is ideal for hydrology, agriculture, construction, or environmental analysis workflows that require on-demand depression depth values validated against Sweden's official boundary.
Side effects
- Coordinate outside Sweden's Natural Earth boundary — request rejected with an error before payment
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Elevation data unavailable for the queried location — no result returned
- Negative or zero difference (point is not in a depression) — may return zero or a specific indicator
- Malformed input coordinates — schema validation error
