HALOWERK Nordic Land – Sweden Surface Elevation
x402
HALOWERK Nordic Land – Sweden Surface Elevation 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 bilinear-interpolated surface elevation (meters) for a WGS84 coordinate inside Sweden, derived from Copernicus DEM GLO-30, with boundary validation against Natural Earth Sweden polygon.

How this service works
Bilinear surface elevation from Copernicus DEM GLO-30. The coordinate is validated against the Natural Earth boundary for Sweden; results outside it are rejected before payment.
Output
Returns the bilinearly interpolated surface elevation in meters for the given WGS84 coordinate, sourced from the Copernicus DEM GLO-30 dataset. Coordinates outside the Natural Earth boundary for Sweden are rejected before any charge is made.
Example use cases
Solar farm site suitability screening
“I'm evaluating a potential solar farm site near Västerås, Sweden — can you get the surface elevation at latitude 59.62, longitude 16.55 so I can assess terrain flatness?”
Hiking route elevation profiling
“I'm planning a hiking trail through northern Sweden and need the terrain elevation at latitude 67.85, longitude 20.22 to understand how hilly that section is.”
Flood risk assessment for Swedish property
“We're doing a flood risk assessment for a property in Gothenburg — please get the surface elevation at latitude 57.71, longitude 11.97 from the Copernicus DEM.”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-elevationWhen to prefer
Choose this endpoint when you need precise point-level surface elevation data specifically within Sweden, backed by the high-resolution Copernicus DEM GLO-30 (~30m posting). It is ideal when boundary enforcement (rejecting non-Sweden coordinates before billing) is important, and when bilinear interpolation quality is preferred over nearest-neighbor. Use over generic global DEM APIs when Sweden-specific validation and per-call micropayment via x402 fit your workflow.
Side effects
- Coordinate outside Sweden boundary: rejected before payment with a boundary validation error
- Coordinate outside overall European coverage range (lat 34–72.5, lon -31.5–40.5): rejected with validation error
- Malformed or missing latitude/longitude fields: returns schema validation error
- DEM data gap at queried location: may return null or error for the elevation value
- Network timeout or service unavailability: returns 5xx error
