Route description (maxspeed, elevation)

I want to ask you if there exists a way to retrieve information such maxspeed and elevation about a given route in a single request.
I know that is possible to retrieve this info doing a singular request for each road, but I’ve not found methods to do it for the entire route.

These info can be retrieved using Snap to roads: Synchronous Snap to Roads | Snap to Roads API
for elevation check the HeightInfo
