HALOWERK Eastern Land – Hungary Surface Elevation
x402
HALOWERK Eastern Land – Hungary Surface Elevation 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 in meters for a WGS84 coordinate within Hungary, 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 Hungary; results outside it are rejected before payment.
Output
A numeric surface elevation value in meters derived from bilinear interpolation of Copernicus DEM GLO-30 data at the requested coordinate. Coordinates outside Hungary's Natural Earth boundary are rejected before any charge is incurred.
Example use cases
Flood risk site assessment
“I need to know the terrain elevation at latitude 46.8, longitude 20.1 in Hungary — it's a potential site for a warehouse and I need to check if it's in a low-lying area.”
Agricultural field altitude check
“Can you pull the Copernicus DEM elevation for coordinates 47.2 latitude, 18.4 longitude in Hungary? I'm planning irrigation and need to know the surface height there.”
Hiking trail elevation lookup
“What's the surface elevation at 48.0 latitude, 20.5 longitude in Hungary? I'm planning a hiking route and want to verify the terrain height at that waypoint.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hu-elevationWhen to prefer
Choose this endpoint when you need precise, Copernicus GLO-30-sourced surface elevation for a specific point within Hungary. It is ideal for applications requiring per-point terrain height rather than raster tiles, and is well-suited for workflows already using the HALOWERK Eastern Land suite of geospatial indicators for Hungary (slope, aspect, soil, land cover). Prefer this over generic elevation APIs when Hungary-specific boundary validation and pay-per-query pricing at $0.003 USDC are acceptable constraints.
Side effects
- Coordinate outside Hungary boundary — rejected before payment with a boundary validation error
- Coordinate within European coverage range but outside Hungary — returns rejection rather than elevation
- Malformed or missing latitude/longitude — returns schema validation error
- Coordinate at or near boundary edge — may return edge-case interpolation result
- Network or upstream DEM data unavailability — may return 5xx error
