HALOWERK Baltic Land – Poland Surface Elevation
x402
HALOWERK Baltic Land – Poland Surface Elevation 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 bilinear-interpolated surface elevation (in metres) from Copernicus DEM GLO-30 for a given WGS84 coordinate, validated against Poland's Natural Earth boundary.

How this service works
Bilinear surface elevation from Copernicus DEM GLO-30. The coordinate is validated against the Natural Earth boundary for Poland; results outside it are rejected before payment.
Output
A bilinear-interpolated surface elevation value in metres derived from the Copernicus DEM GLO-30 dataset for the queried WGS84 coordinate. The response is returned only if the coordinate falls within Poland's Natural Earth boundary; out-of-bounds coordinates are rejected before any charge is applied.
Example use cases
Construction site elevation check
“I need to know the ground elevation at latitude 52.406 and longitude 16.925 in Poland — it's a potential construction site and I need the terrain height from the Copernicus DEM.”
Hiking trail altitude profile point
“Can you get me the surface elevation at lat 49.295, lon 19.982 in Poland? I'm building an altitude profile for a hiking route in the Tatra foothills.”
Flood risk terrain assessment
“What's the terrain elevation at latitude 51.107 and longitude 17.038 in Poland? I'm assessing flood risk for that area and need the DEM height.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-elevationWhen to prefer
Choose this endpoint when you need a precise, single-point terrain elevation for a coordinate within Poland, backed by the high-resolution Copernicus GLO-30 DEM (~30m posting). It is ideal when boundary validation against Poland is required (coordinates outside Poland are rejected before billing). Prefer this over generic global elevation APIs when accuracy within Poland and cost-per-call predictability ($0.003 USDC) matter, and when the Copernicus DEM data lineage is important for your use case.
Side effects
- Coordinate outside Poland boundary: request rejected before payment with a boundary validation error
- Coordinate within European coverage range but outside Poland: rejected by Natural Earth boundary check
- Latitude or longitude outside the published European coverage bounds (lat 34–72.5, lon -31.5–40.5): input validation error
- Malformed or missing latitude/longitude fields: schema validation error
- Service unavailability or upstream DEM data error: HTTP 5xx response
