ASK HN: TD Ameritrade has an Trading API

I thought I would just bring this to the attention of everyone, as I'm not completely sure they are advertising it as of yet.

But it looks like TD Ameritrade has revamped their API. https://developer.tdameritrade.com/

About 6 months ago they had an API that was last updated in maybe 2012? It appears that it hadn't been supported either. But it looks like they revamped with a new API and twitter bootstrap design. I think it might be in Beta, because there are spelling mistakes and just some installation instructions that don't make a lot of sense. It also has that out of the "twitter bootstrap" box feel.

My question is has anybody had any experience working with the new API at TD Ameritrade? Any repos that I could contribute to, etc?

About 6 months ago when I found out TD Ameritrade had an unsupported API, I moved over to Interactive Brokers and used the SDK ib_insyc (https://github.com/erdewit/ib_insync) to develop my trading algo. It works, but at times it can be serious headache. Not necessarily ib_insyc, but Interactive Brokers API.
