## Before you call it

1. Call `quote_service` before `pay_service`; quotes cost nothing
2. Ask the person to open the `setup_delegation` URL once; you can't mint the first key or budget yourself
3. Branch on the error `code` and retry only when `retryable` is true
4. Create a small, short delegation per task; cards stop at $10.00 across delegations unless the owner raises it
5. Use `sandbox:` keys and mcp.sandbox.nevermined.app until the flow works

## Connect

```bash
