Check the current request terms and wallet response before proceeding. Payment, tool execution and the saved work receipt are distinct records.
Paying from an AgentKit wallet
Before approving, inspect the amount, recipient and network shown in your wallet. Only authorize a request you intended to make, and keep any agent spending policy within a limit you control.
A payment approval and the tool's work result are separate events.
Calling tools after payment
- Wait for the payment provider to confirm the payment response.
- Repeat or resume the same requested call through the client.
- Inspect the returned work status and its receipt separately from the payment record.
