I haven't tackled payments, but I've run an agent with SSH access to a production server and real API keys for a few weeks. The trust question you're circling ("would you trust an AI with $500") is the interesting part. My answer so far: yes for reversible actions, not yet for irreversible ones. Deleting a file, sending an email, making a payment — these need a different approval model than reading a database or running a query. The hard problem isn't capability, it's building infrastructure that distinguishes "can do" from "should do without asking.

And i want to build an agent capable to do automated investment. so, to the question "has" anyone...?" i believe yes, my role model is Jim Simons from Renaissance. He did.
