The top-level links object MAY contain the following members:

• "self" - a link for fetching the data in the response document.
• Pagination links for the primary data, as described below.

I believe we aren't even using this key yet, correct? Since this is a MAY requirement, we technically don't need to do anything here, although paging is something we absolutely ought to support eventually, and the self key is nice to have and probably easy to add.
