The agent generates a secure, limited-use virtual card link for the human to use directly in their browser for a specific merchant.
The agent calls create_one_time_card with the expected spend cap and merchant details to initiate a card issuance request. It then immediately calls wait_for_one_time_card to monitor the approval status. Once the human approves via the provided link, the agent retrieves the secure reveal URL and presents it to the human, who can then use the card details for checkout.
