HALOWERK Southern Land – Spain Depression Depth
x402
HALOWERK Southern Land – Spain 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 elevation difference between the neighborhood mean and center cell elevation (depression depth) for a given coordinate within Spain.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Spain; results outside it are rejected before payment.
Output
A numeric value representing the positive difference (in meters) between the mean elevation of the surrounding neighborhood cells and the center cell elevation at the queried coordinate, indicating how much the center point is depressed relative to its surroundings. Returns an error if the coordinate falls outside Spain's Natural Earth boundary.
Example use cases
Agricultural waterlogging risk assessment
“I'm scouting farmland near Seville — can you check the depression depth at 37.35 latitude, -5.97 longitude? I want to know if the center of that plot sits lower than the surrounding area, which could mean waterlogging risk.”
Vineyard site drainage evaluation
“I'm evaluating a potential vineyard plot in La Rioja at coordinates 42.46 latitude, -2.58 longitude. Can you tell me the terrain depression depth there so I know if water would pool at the center?”
Solar farm terrain suitability check
“We're planning a solar installation near Valencia at latitude 39.47, longitude -0.38 — pull the depression depth for that spot so we can understand how the center elevation compares to the neighborhood mean before we commit.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-depression-depthWhen to prefer
Choose this endpoint when you need a precise terrain depression depth metric (positive neighborhood-mean minus center elevation) for a specific coordinate within Spain, particularly for land assessment use cases such as agriculture site selection, drainage analysis, or topographic profiling. It is the right choice when you need a single-point Spain-validated computation rather than a generic DEM query or multi-country terrain service.
Side effects
- Coordinate outside Spain's Natural Earth boundary — request rejected before payment is charged
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Invalid or missing latitude/longitude values — input validation failure
- Payment failure via x402 protocol — call not processed
