MoonPay launched PayBox today—a payment vault that plugs into Claude and ChatGPT and lets AI agents, software programs that complete tasks autonomously on your behalf, to actually spend money for you. The mechanics are fairly straightforward. The vault acts as a secure digital safe that stores both crypto wallets and payment cards. You tell the chatbot what you want. The AI then lines up the transaction. You approve it with a passkey (a secure digital key stored on your phone or device, like Face ID for payments). The money then moves.
