Hello @Brett Jackson , Thanks for using Microsoft Q&A Platform.
DALL-E does not support inpainting/editing at this time. Currently, we only support the image generations API.
Yes, we don't have public documentation yet, but in the onboarding approval email, you might have received a link to the private docs as DALL-E is in private preview. At this moment we only have this documentation. Sorry for any inconveniences. Hope you understand.
I hope this helps.
Regards,
Vasavi
