HALOWERK Baltic Land – Lithuania Surface Elevation (Copernicus DEM GLO-30)
x402
HALOWERK Baltic Land – Lithuania Surface Elevation (Copernicus DEM GLO-30) 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 meters for a WGS84 coordinate validated to lie within Lithuania, sourced from the Copernicus DEM GLO-30 dataset.

How this service works
Bilinear surface elevation from Copernicus DEM GLO-30. The coordinate is validated against the Natural Earth boundary for Lithuania; results outside it are rejected before payment.
Output
A numeric surface elevation value in meters, bilinearly interpolated from the Copernicus DEM GLO-30 raster at the requested coordinate. Coordinates outside the Lithuania boundary polygon (per Natural Earth) are rejected before any charge is applied.
Example use cases
Construction site terrain assessment
“I need the ground elevation for the site at latitude 55.9333, longitude 23.3167 in Lithuania — we're planning a building project there and need the Copernicus DEM height.”
Hiking route altitude profiling
“Can you get me the surface elevation at latitude 54.2710, longitude 24.0338 in Lithuania? I'm mapping out a hiking trail and need terrain height data.”
Flood risk pre-screening
“What's the terrain elevation at latitude 55.1736, longitude 24.3573 in Lithuania? I'm doing a preliminary flood risk assessment for that area and need the DEM elevation in meters.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/lt-elevationWhen to prefer
Use this endpoint when you specifically need high-resolution (GLO-30, ~30m) Copernicus DEM surface elevation for a point coordinate confirmed to be within Lithuania. The pre-payment boundary validation against the Natural Earth Lithuania polygon means coordinates outside Lithuania are rejected for free, avoiding wasted charges. Prefer this over generic elevation APIs when Lithuanian coverage and Copernicus DEM provenance are required. For other Baltic countries or broader European coverage, sibling endpoints on the same platform may apply.
Side effects
- Coordinate outside Lithuania boundary — rejected with an error before payment is charged
- Latitude or longitude outside the published European coverage bounds (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 — request not processed
- Server-side DEM data access error — service unavailable response
