Dispatches on this topic
- JPMorgan closed its accounts to agents it cannot identify. Two days later, Proof published a way to knock.
On its October 13 earnings call, JPMorgan said outside AI agents may not act inside customer accounts, and Jamie Dimon warned of 'rogue agents' and a 'liability transfer.' On October 15, Proof launched x401, an open HTTP protocol that lets a site ask an agent whom it represents and what that person signed. A blanket block is what a bank does when it has no signal to read. The useful question for agents is what signal to carry.
