Is there a way to get coauthors in the API?

GitHub implemented the concept of coauthors on a commit a while back.

For example

Here the web GUI indicates 2 authors for this commit as it should.

However, when I query the API for this commit, it only returns the first author, scottwn (that’s me). Is there a way to get the coauthors from the API in the same way that they appear on the GUI?
