Can I check the MRR and ARR metrics for a specific customer contract?

Yes. The `get_contract_metrics` tool allows your AI agent to retrieve real-time Monthly Recurring Revenue (MRR), Annual Recurring Revenue (ARR), and Total Contract Value (TCV) for any specific subscription ID.

How do I see if a customer's latest invoice has been paid?

You can use the `list_invoices` tool. Your AI agent will return a list of recent invoices along with their current status, such as 'DRAFT', 'POSTED', or 'PAID', helping you audit financial activity through chat.

Is it possible to terminate a subscription via conversation?

Absolutely. Using the `cancel_subscription_version` tool, you can instruct your agent to terminate a specific subscription. You'll need to provide the subscription and version IDs plus the effective cancellation date.
