HALOWERK Eastern Land – Croatia Elevation Lookup
x402
HALOWERK Eastern Land – Croatia Elevation Lookup is a paid API for AI agents from ostland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns bilinear-interpolated surface elevation (metres) for a WGS84 coordinate inside Croatia using Copernicus DEM GLO-30, rejecting coordinates outside Croatian boundaries before charging.

How this service works
Bilinear surface elevation from Copernicus DEM GLO-30. The coordinate is validated against the Natural Earth boundary for Croatia; results outside it are rejected before payment.
Output
A bilinear-interpolated surface elevation value in metres above sea level for the requested WGS84 coordinate, derived from the Copernicus DEM GLO-30 30-metre resolution dataset. Coordinates outside the Croatian boundary are rejected before the payment is processed.
Example use cases
Site suitability for solar farm
“I'm evaluating a potential solar farm site near Dubrovnik at latitude 42.6507, longitude 18.0944 — can you pull the Copernicus GLO-30 elevation for that Croatian coordinate so I can assess terrain height?”
Hiking trail elevation profiling
“I'm planning a trail in Plitvice Lakes National Park and need the surface elevation at latitude 44.8654, longitude 15.6219 in Croatia — give me the DEM height in metres.”
Flood risk baseline assessment
“For a flood risk study, what is the ground elevation at latitude 45.3271, longitude 18.4143 in Croatia according to the Copernicus DEM?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hr-elevationWhen to prefer
Choose this endpoint when you need precise, Copernicus GLO-30-based surface elevation for a specific point within Croatia and want boundary pre-validation to avoid paying for out-of-scope coordinates. Prefer it over general-purpose elevation APIs when Croatia-specific validation and per-call micro-payment via x402 are acceptable, and when bilinear interpolation quality from a 30m DEM is sufficient for your use case.
Side effects
- Coordinate outside Croatia boundary — rejected before payment with a 4xx error indicating the point falls outside the validated region
- Coordinate within European coverage bounds but outside Croatia — rejected by Natural Earth boundary check
- Invalid latitude/longitude values outside the published European range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Service unavailability or upstream DEM data error — 5xx response
