How to work with Wiki repo on GitHub (via API or git)?

I use nodeJS script to fetch information about contributors to my project. And I would do the same to WIki. The API return 404 for wiki repo, so I’ve cloned the repo using https://github.com/jcubic/jquery.terminal.wiki.git but it also is useless because it seems that it only gets new data when it’s cloned. The repo is not updated with new edits when using git pull.

I can use this repo and update the copy at git@github.com:jcubic/jquery-terminal-wiki.git but the Wiki repo is not synched.
