The API isn't live yet.
We use the same API in the Clew web apps, so we're actually actively using and testing it in production. At the moment we're working on buttoning up documentation and other supplementary material that has to exist around the API for it to be useful and successful.
This includes the launch of this forum; as a way for us to actively engage with the developer community and support users once it's live.
So you could say we're one step closer. Once we're done with the documentation (next 1-2 months) and a bunch more testing, it'll be live and accessible to any Clew user.
