Zwift API?

Hi,
Zwift has cool features for virtual riding and I’m really enjoying them.
The feedback of POWER toward my Kickr is so good.
But I have some more questions.

Do you have some APIs for more than power output? (ex.: gradient, wind speed)
Maybe I could DIY for fan or incliner.
It would make the zwift riding more realastic.
Thanks
