The Voice AI API lets you programmatically create and manage AI voice agents — automated callers that handle inbound or outbound calls using configurable behaviors and actions. Use it to build custom voice automation, configure agent scripts, attach actions (such as transferring calls or booking appointments), and retrieve detailed call logs.
