HALOWERK Southern Land – PT Depression Depth
x402
HALOWERK Southern Land – PT Depression Depth is a paid API for AI agents from suedland.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 for a given coordinate within Portugal, measuring topographic depression depth.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
A numeric value representing the positive elevation difference (in metres) between the mean elevation of the surrounding neighborhood cells and the center-point elevation, indicating how depressed the location is relative to its local terrain. Coordinates outside the Portugal boundary are rejected before any charge is incurred.
Example use cases
Flood-prone site assessment
“I'm evaluating a plot at 37.9214° N, 8.8243° W in Portugal — can you check how deep the terrain depression is there so I can estimate flood water accumulation risk?”
Vineyard drainage planning
“We're planning a new vineyard at latitude 41.15, longitude -8.61 in Portugal and need the local depression depth to understand if the site will have drainage problems.”
Environmental restoration site selection
“Can you calculate the depression depth at 39.4, -8.2 in Portugal? We're looking for natural water-collecting hollows suitable for wetland restoration.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-depression-depthWhen to prefer
Use this endpoint when you need a precise, per-point measure of terrain concavity or hollow depth specifically within Portugal. It is ideal for agricultural site assessment, hydrological modelling, drainage analysis, or land evaluation tasks where knowing how depressed a point is relative to its neighbors matters. Prefer this over generic DEM APIs when you need boundary-validated, pay-per-query elevation depression data restricted to Portugal.
Side effects
- Coordinate outside Portugal boundary — request rejected before payment, returns validation error
- Latitude or longitude outside the European coverage bounding box (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- No elevation data available for the queried cell — returns data-not-found error
- Depression value is zero or negative (i.e. location is not a depression) — may return 0 or null
- Network or payment processing failure via x402 protocol
