About

Vapi is a developer platform for voice AI: you configure an assistant (voice, model, prompt, tools), and Vapi handles the telephony, speech-to-text, and text-to-speech plumbing over phone or web calls. Every new account gets free starter credits without a credit card, and the API covers assistants, calls, phone numbers, and tool/function calling mid-conversation.
