> If I'm understanding you correctly: they changed that policy, you can now use 3rd party software unofficially with the undocumented Claude Code endpoint, and their servers auto-detect this and charge you extra for it?

That’s correct. It’s more like a convenience technicality: you can use your sub account, but you’re paying extra. So it doesn’t really count towards your subscription in any way.

Subscriptions can buy extra credits against a 30% discount, though, so it’s a decent amount cheaper than actual API, but still prohibitively expensive.
