Does Azure ARM REST API provide a way to get a list of available regions?
I can see that the classic REST API provides such a list as described here:

But I can't see its equivalent for ARM.
To list the locations for an Azure Subscription using ARM API, please see this link: https://msdn.microsoft.com/en-us/library/azure/dn790540.aspx.
However please keep in mind that not all resources are available in all locations. If you want to find out the locations where a particular resource type is available, you would need to fetch information about the provider of that resource type.
