Comment (by bpetty):

 I see posts_per_page, and page, but I'm not currently seeing any value
 indication in the schema for total number of items in a paged collection.
 I know some REST APIs will include a "last" link header, leaving it open
 for some parsing and calculations to get the total number of items. I
 still would like to see a total count somewhere else not requiring extra
 URL parsing, but I'm not sure where the best place for this would be
 honestly.
