INCORRECT. The full MTProto API has updateChatUserTyping, but the Bot API does NOT support receiving typing indicators. Bots can SEND typing status but cannot RECEIVE it.

PARTIALLY INCORRECT. Claude Max starts at $100/month (5x tier), not $200. The $200 figure might refer to Pro annual billing ($200 upfront) or a higher Max tier (20x). Current pricing shows Max 'From $100' per person.
