HALOWERK Atlantic Land – France Surface Elevation
x402
HALOWERK Atlantic Land – France Surface Elevation is a paid API for AI agents from atlantikland.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 France, sourced from Copernicus DEM GLO-30, with boundary validation against Natural Earth France polygon.

How this service works
Bilinear surface elevation from Copernicus DEM GLO-30. The coordinate is validated against the Natural Earth boundary for France; results outside it are rejected before payment.
Output
A numeric surface elevation value in meters derived from bilinear interpolation of the Copernicus DEM GLO-30 raster at the requested coordinate. The response is only returned if the coordinate falls within the Natural Earth boundary for France; out-of-bounds coordinates are rejected before any charge is applied.
Example use cases
Site suitability for rural construction
“Can you look up the terrain elevation at latitude 44.1234, longitude 2.5678 in France? I need the altitude from the Copernicus DEM to assess whether this plot is suitable for building.”
Hiking trail elevation profile point
“I'm building a trail elevation profile — what's the surface elevation at lat 45.9236, lon 6.8651 in France according to the Copernicus GLO-30 dataset?”
Flood risk assessment for a parcel
“What is the DEM elevation at latitude 47.2184, longitude -1.5536 in France? I need the ground height to estimate whether this parcel is in a low-lying flood-prone area.”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/fr-elevationWhen to prefer
Use this endpoint when you need a precise, single-point surface elevation for a coordinate confirmed to be within France, sourced from the high-resolution Copernicus DEM GLO-30 (30 m posting). It is preferable over generic elevation APIs when France-specific boundary validation is required, when Copernicus DEM provenance matters (e.g. for regulatory or environmental workflows), or when bilinear interpolation quality is needed. It is NOT suitable for coordinates outside France or for batch/gridded elevation queries.
Side effects
- Coordinate outside France boundary: request is rejected before payment with a boundary validation error
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation error
- Missing latitude or longitude parameter: request fails with a parameter validation error
- DEM data gap or no-data cell at the exact coordinate: may return null or an error value
- Network or payment failure: x402 payment not settled, request not processed
