Voice agents

One identity and payments layer.
Every voice-agent platform.

Drops into your existing agent, works with your existing payment processor. Your agent creates a Checkout Session; Ringup recognizes the caller by phone number, charges their saved card on the merchant’s own processor, and no card number is ever read aloud. Two ways to integrate: a native handoff on Vapi, or a call transfer everywhere else. Pick your platform for the exact wiring.

Add payments to your Vapi voice agent with one CLI command.
