Build Voice AI That Actually Talks to Your Customers
Arbol gives you a REST API to deploy AI agents that handle real phone conversations. Create agents that answer customer calls, qualify leads, schedule appointments, or run outbound campaigns—all without hiring a call center.Terminology: In the Arbol dashboard, agents are called “AI Employees” for end users. In this API documentation, we use “agents” for technical consistency.
