Using the Google Photos api, is there any way to get the ID of the cover photo of an album? So, for example, I could query the metadata on the cover photo? The only thing I see is the coverPhotoBaseUrl, which doesn't help me.

I agree, this is something that would be quite useful to include, in addition to the cover photo base URL. Please follow along on the issue tracker - you can 'star' the issue to be notified of any updates.
Unfortunately there is no work around at the moment.
