Doesn't team bill API rates?

No that’s enterprise accounts. Team accounts are similar to regular Pro and 5x Max accounts in both price and features.

Team is 1.25x the price of personal accounts, but supposedly also gives 1.25x more usage.

And Teams Premium was previously needed for any claude-code at all.

I'm not sure why I'm being downvoted, in November last year, the regular teams tier did not let you use claude code, premium was required.

They've changed it since, but that's why I said "previously".
