Doc/api ref site

[sandytang886]

please help me review branch doc/api-ref-site

[metalalive]

For now, the 3 API endpoints in this doc site look good to me.
If other reviewers don't respond yet for too long (like one or two days), please tag them at here or message them for this PR.

@KalpasWang

you didn't approve the PR, do you know how to do this ?
Go to the tab Files Changed, it lists all files changed in the PR.
You click the checkbox along with the text viewed, for each file after reading it,
think about whether the change / the code makes sense (<-- important, code review should be a way of communication, since this team embrace async communication)
then finally click approve button with your comment.

sorry, I've never reviewed other people's PR.
I approved it, is there anything I'm still missing?
