HALOWERK Baltic Land – Latvia Depression Depth
x402
HALOWERK Baltic Land – Latvia Depression Depth is a paid API for AI agents from baltikum.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 cell elevation (depression depth) for a given coordinate within Latvia.

How this service works
Positive difference between the neighborhood mean and center elevation. The coordinate is validated against the Natural Earth boundary for Latvia; results outside it are rejected before payment.
Output
Returns a numeric value representing the positive difference (in meters) between the mean elevation of the surrounding neighborhood cells and the elevation at the queried center coordinate, indicating how depressed the terrain is at that point. Coordinates outside Latvia are rejected with a validation error before any payment is charged.
Example use cases
Flood risk site assessment in Latvia
“I'm evaluating a property near Jelgava, Latvia at 56.651 latitude, 23.721 longitude — can you tell me how deep the terrain depression is there compared to the surrounding neighborhood? I need it for a flood risk report.”
Agricultural drainage planning
“We're planning drainage works for a field in Latvia at coordinates 57.12 latitude, 25.30 longitude. What's the depression depth at that point so we know how much water could pool there?”
Infrastructure routing in low-lying areas
“Before we route a road through this Latvian site at 56.50 latitude, 27.05 longitude, can you check the local terrain depression depth so we can avoid building in a sink?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/lv-depression-depthWhen to prefer
Use this endpoint when you need the topographic depression depth (neighborhood mean minus center elevation) for a specific point within Latvia. It is ideal for hydrological analysis, flood risk assessment, agricultural drainage planning, or infrastructure siting where local sink depth matters. Prefer this over general elevation APIs when you specifically need the depression metric relative to surroundings rather than absolute elevation.
Side effects
- Coordinate outside Latvia boundary — rejected by Natural Earth validation before payment, returns error
- Coordinate outside the broader European coverage bounding box — schema validation failure
- Non-numeric or malformed latitude/longitude values — schema validation error
- Network timeout or service unavailability — standard HTTP 5xx error
