HALOWERK Baltic Land – Surface Elevation (Germany)
x402
HALOWERK Baltic Land – Surface Elevation (Germany) 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 for a WGS84 coordinate within Germany, derived from Copernicus DEM GLO-30, with boundary validation rejecting points outside Germany.

How this service works
Bilinear surface elevation from Copernicus DEM GLO-30. The coordinate is validated against the Natural Earth boundary for Germany; results outside it are rejected before payment.
Output
A surface elevation value in metres derived from bilinear interpolation of the Copernicus DEM GLO-30 30m grid for the queried coordinate. The response is only returned if the coordinate passes validation against the Natural Earth boundary for Germany; otherwise the request is rejected before any charge is made.
Example use cases
Flood risk site screening
“We're assessing flood risk for a site near Frankfurt — can you look up the terrain elevation at latitude 50.110 longitude 8.682 in Germany?”
Hiking trail altitude profiling
“I'm planning a hike and need to know the surface elevation at latitude 47.421 longitude 10.985 in the Bavarian Alps area — what does the GLO-30 DEM say?”
Solar farm feasibility check
“For our solar farm feasibility study, can you pull the Copernicus DEM elevation for the coordinate latitude 51.340 longitude 12.375 inside Germany?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/de-elevationWhen to prefer
Choose this endpoint when you need precise, high-resolution (30m GLO-30) surface elevation for a specific point location within Germany, and you want automatic boundary validation ensuring you are charged only for valid German coordinates. Prefer it over generic elevation APIs when working within the German territory and when Copernicus DEM provenance and bilinear interpolation accuracy matter for your use case (e.g. civil engineering, environmental modelling, terrain analysis).
Side effects
- Coordinate outside Germany boundary: request rejected before payment, no elevation returned
- Coordinate within European coverage bounds but outside Germany: rejected by Natural Earth boundary check
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5): validation error
- Malformed or missing latitude/longitude fields: schema validation error
- Payment failure via x402 protocol: transaction not completed, no data returned
