Anthropic clamping down on non-first party clients using their subscription plans may also have something to do with it.
I avoided it after Anthropic's rampage against `claude -p` to stop Openclaw and didn't want to get hit in the crossfire. It was hard to follow their back and forth, but it seems that's done now?
Hard for one person to keep up with a product that ships updates multiple times a day.
Note “official” in the request… there are unofficial ones.
