x402
HALOWERK Atlantic Land – France Depression Depth is a paid API for AI agents from atlantikland.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 point elevation (depression depth) for a given coordinate within France.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for France; 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 and the center-point elevation at the queried coordinate, indicating how deep a topographic depression is at that location. Coordinates outside the France Natural Earth boundary are rejected before any charge is applied.
Example use cases
Flood risk site assessment
“I'm evaluating land near Bordeaux at latitude 44.84, longitude -0.58 — can you tell me the depression depth there so I know how much lower the center sits relative to its surroundings?”
Agricultural drainage planning
“For a farm plot at 47.2, 1.5 in central France, what is the local elevation depression depth? I need to understand how water might pool at that location.”
Urban construction terrain check
“We're planning a building project in Lyon at coordinates 45.75 latitude, 4.85 longitude. Can you give me the depression depth — how far below its neighborhood mean elevation that point is?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/fr-depression-depthWhen to prefer
Choose this endpoint when you need localized depression depth — the positive elevation gap between a neighborhood mean and a center point — specifically for coordinates within France. It is validated against the Natural Earth France boundary before charging, making it safe to call without pre-filtering. Prefer this over generic elevation APIs when you need this specific terrain morphology metric rather than raw elevation or slope.
Side effects
- Coordinate outside France boundary: request is rejected before payment with a validation error
- Latitude or longitude out of published European coverage range (lat 34–72.5, lon -31.5–40.5): rejected with schema validation error
- Invalid coordinate types (non-numeric values): schema validation failure
- Network timeout or service unavailability: HTTP 5xx error
