Can I send a physical check through the agent?

Yes! Use the `send_physical_check` tool. Provide the recipient's name, email, and amount. Checkbook.io will print and mail a physical check to the recipient.

How do I check if a check has been deposited?

Use the `get_check_details` tool with the unique check ID. Your agent will fetch the current status (e.g., IN_PROCESS, PAID, VOID).

Where do I find my Checkbook API Key and Secret?

Log in to your Checkbook.io account and navigate to **Settings -> Developer**. You can generate and copy your API Key and Secret from that section.
