Ernest is on fire lately, and he has now confirmed that the API will be unlocked in the next release of kbin!
It remains to be seen if Artemis automatically discovers that the API is available, or if some further work is needed by Hariette to enable things on the Artemis side. I hope she's doing well.
I don't know anything concrete, but Ernest is giving a lot of updates over at /m/kbinDevlog. He's apparently testing the API implementation more or less as we speak. :)
