What agents CAN’T do
These features exist in the wallet UI, but agents cannot access them. Only you can:- Set spending limits — Configure max spend per call and per session in the wallet UI. Agents respect these limits but can’t change them.
- Transfer funds — Send USDC to other addresses. Agents can only pay for x402 services, not send to arbitrary addresses.
- Add funds — Use Coinbase Onramp to add USDC. Agents can’t initiate onramp flows.
