HALOWERK Nordic Land – Denmark Surface Elevation (Copernicus DEM GLO-30)
x402
HALOWERK Nordic Land – Denmark Surface Elevation (Copernicus DEM GLO-30) is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns bilinearly interpolated surface elevation in metres for a WGS84 coordinate inside Denmark, sourced from Copernicus DEM GLO-30.

How this service works
Bilinear surface elevation from Copernicus DEM GLO-30. The coordinate is validated against the Natural Earth boundary for Denmark; results outside it are rejected before payment.
Output
A numeric surface elevation value in metres derived from bilinear interpolation of the Copernicus DEM GLO-30 raster at the requested WGS84 coordinate. The response is returned only if the coordinate falls within the Natural Earth boundary of Denmark; requests outside that boundary are rejected before any charge is applied.
Example use cases
Site feasibility check for solar farm
“Can you tell me the ground elevation at 56.13°N, 10.21°E in Denmark? I'm assessing terrain height for a potential solar installation site.”
Flood risk point elevation lookup
“What is the surface elevation at latitude 55.47, longitude 8.45 inside Denmark? We're modelling flood exposure and need the Copernicus DEM height for that coordinate.”
Cycling route elevation profiling
“I'm planning a cycling route across Denmark — can you get me the Copernicus GLO-30 elevation at 55.86°N, 9.85°E so I can start building an elevation profile?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/dk-elevationWhen to prefer
Choose this endpoint when you need precise, per-point surface elevation for a coordinate known to be within Denmark and want Copernicus GLO-30 quality (~30 m resolution) with bilinear interpolation for sub-pixel accuracy. It is ideal for GIS enrichment, site assessment, flood modelling, or route profiling workflows where a pay-per-call micro-payment model is acceptable and boundary pre-validation saves unnecessary charges. Prefer alternatives if you need bulk/batch elevation queries, coverage outside Denmark, or a different DEM source such as SRTM.
Side effects
- Coordinate outside Denmark boundary — rejected before payment, returns a validation error
- Latitude or longitude outside the accepted European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed or missing latitude/longitude fields — returns a 400-level error
- Service unavailable or upstream DEM data issue — returns a 5xx error
