 # Appointment Booking Agents Vertical Starter Kit
 
+A modular and AI-powered appointment booking agent designed to streamline scheduling for businesses, starting with dental clinics. Built with LangGraph, Composio, and AI Telephony, this agent integrates Google Calendar and Gmail to manage appointments, send confirmations, and handle outbound phone calls.

+Users can check available time slots, confirm bookings, and receive queue updates via email, call, or message. The system is highly customizable, supporting alternative CRM, mail services, and voice providers like Twilio or Vapi. Deployed on Vercel and LangGraph Cloud, with robust testing via LangSmith and LLM unit tests.
