Maven

Payments for AI voice agents and chatbots

Maven is a payments API for conversational agents that collects card details during live voice calls or inline in chat widgets. Card data is captured by Maven rather than the customer's servers, while charges are processed through the customer's own payment gateway, keeping card digits out of the customer's stack.

The platform supports 25 gateways or a bring-your-own PCI-compliant endpoint, with signed webhooks for both voice and chat. Voice sessions are created through a single API call that returns a phone number and SIP URI for transferring the caller, while chat payments mount via a script tag into an iframe. Integrations include Vapi and Retell, plus any agent stack via the API. Voice, script, rules, and theme are configurable per app, including voice providers such as ElevenLabs, Deepgram, Cartesia, and Rime. Card collection supports voice and keypad input, optional ZIP address verification, and card brand allowlists, with a tokenize mode for storing cards without charging.

Maven is aimed at teams building agents for commerce, restaurants, healthcare, home services, insurance, travel, salons, and debt collection. It is available with a free starting plan, and the pages do not specify further packaging details.
