The basic information is available in the disk resource:

/api/disks/{disk:id}
/api/vms/{vm:id}/disks/{disk:id}

There you will find three values:

  <size>...</size>
  <provisioned_size>...</provisioned_size>
  <actual_size>...</actual_size>

I think that the <actual_size> is what you are looking for.

For a particular storage domain you can also see some aggregated
information, in tue /api/storagedomains/{storagedomain:id} resource:

  <available>...</available>
  <used>...</used>
  <committed>...</committed>
