Having never given labs.openai.com money, this is what I get:
Updates to DALL·E
We are no longer allowing new users to DALL·E 2. DALL·E 3 has higher quality images, improved prompt adherence, and we’ve started rolling out image editing.
Purchasing new credits was disabled May 1.
If you have a credit balance, I would expect you to still have some method of generating for your money, but it seems like the site is winding down.
DALL-E 2 by API is $0.02 per image, instead of the $0.135 per iimage that the labs site cost when you had to buy 115. So any balance you have lost is max $2 via the API.
It is clear that contrary to the DALL-E 3 announcement, it is not coming to labs “in the fall”.
