Before you call either
Nevermined API + MCP
- Call
quote_servicebeforepay_service; quotes cost nothing - Ask the person to open the
setup_delegationURL once; you can't mint the first key or budget yourself - Branch on the error
codeand retry only whenretryableis true - Create a small, short delegation per task; cards stop at $10.00 across delegations unless the owner raises it
- Use
sandbox:keys and mcp.sandbox.nevermined.app until the flow works
Payman Genie MCP
- Pass the person's request to
ask_geniein their own words; don't pick accounts or fill payment fields - On
needs_approval, stop and tell the person; approval happens in their Genie account - Retry only after
NOTHING_RANorBUSY, never afterOUTCOME_UNKNOWN - Treat
doneas acted, not settled; check the activity history before confirming a payment - Sign-ins from bridge 0.3.x lack
genie:self; log out and sign in again to use the self-service tools
