x402
HALOWERK Nordic Land – Depression Depth (No-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 difference between neighborhood mean elevation and center-point elevation (depression depth) for a coordinate in Norway.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Norway; results outside it are rejected before payment.
Output
A numeric value representing the positive difference (in meters or terrain units) between the mean elevation of the surrounding neighborhood and the center-point elevation at the queried coordinate. If the center is higher than or equal to the neighborhood mean, the depth is zero. Coordinates outside the Norway boundary are rejected before any computation or payment is processed.
Example use cases
Flood risk assessment for a Norwegian site
“I'm evaluating a plot near Bergen, Norway at latitude 60.39, longitude 5.33 — can you tell me how much lower the center point is compared to the surrounding terrain? I want to understand if it sits in a depression that could pool water.”
Agricultural drainage planning in Norway
“For our farm field at latitude 63.43, longitude 10.39 in Norway, what's the depression depth? We need to know if the terrain dips significantly compared to its neighbors before we design our drainage system.”
Infrastructure siting survey in Oslo region
“We're planning a construction project at latitude 59.95, longitude 10.85 — can you check the depression depth at that location? We want to know how far the center elevation falls below the neighborhood mean to assess waterlogging risk.”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/no-depression-depthWhen to prefer
Use this endpoint when you need a precise terrain depression metric (neighborhood mean minus center elevation) for a specific point in Norway. It is especially useful for hydrology, drainage analysis, flood risk modeling, or agricultural/infrastructure siting where low-lying terrain pockets matter. Prefer this over generic DEM lookup endpoints when you specifically need the depression depth (not raw elevation or slope) and your target is within Norway.
Side effects
- Coordinate outside Norway boundary: request rejected before payment, error indicating coordinate is outside valid coverage area
- Coordinate within European coverage bounding box but outside Norway polygon: validation failure returned
- Latitude or longitude out of the published European bounding box range: schema validation error
- Location in Norway but with no available elevation data: may return null or error
- Network timeout or service unavailability: HTTP 5xx error
