One line in @agenticscredit's docs interested me more than another score screenshot. The scoring endpoint is read only. Reading a wallets rating and performing a state changing action are separated. The partner API also fails closed when authentication keys are missing. No keys means an error, not an accidentally open endpoint. That sounds like boring backend plumbing. It is also where agent infrastructure gets serious. Once autonomous software can interact with financial systems, intelligence is only half the problem. The other half is what happens when permissions, authentication or configuration fail. Good infrastructure should make unsafe defaults difficult. The flashy part is autonomy. The part worth studying is containment.
