Vapi

Vapi is a developer platform for building voice AI agents that make and receive phone calls and connect to APIs.

Vapi

Vapi lets developers create voice agents using speech-to-text, language models, and text-to-speech. Agents can handle phone calls, web voice conversations, tools, APIs, structured outputs, and transfers between specialized assistants.

It is used for customer support, sales, appointment scheduling, medical triage, and ecommerce workflows. Usage is billed by the minute, with model, voice, transcriber, and telephony costs generally charged separately or passed through. Optional packages add support, capacity, retention, and service-level commitments.
