Retrive programmatically SharePoint Online storage space

Copper Contributor

How can I retrieve programmatically SharePoint Online allocated (purchased) storage space of the whole tenant, which is visualized "In the upper right of the page":

In report below, it is possible to retrieve used storage space, but not the allocated.

You could try to use the PowerShell Get-SPOSite with the --StorageUsageCurrent parameter.
Run it for all sites and calculate the total. 
Not sure if this would work in your case.
