An Azure service that provides geospatial APIs to add maps, spatial analytics, and mobility solutions to apps.
It looks like you might be requesting static map images rather than map tiles. Map tiles don't have any copyright or logo's on them, but the static map image API always adds those. Your URL for tiles should look something like this:
https://atlas.microsoft.com/map/tile?api-version=2024-04-01&tilesetId=microsoft.terra.main&zoom={z}&x={x}&y={y}&tileSize=512&view=Auto
Documentation on this service is here: https://learn.microsoft.com/en-us/rest/api/maps/render/get-map-tile?view=rest-maps-2026-01-01&tabs=HTTP
Note that the "terra" tiles are only available for zoom levels 0 through 6. Those tiles are PNG I believe.
The shaded relief map style you can get in the web SDK is not exposed via the public API's. That's actually multiple tile layers, vector and raster, being combined on the client.
