In this tutorial, I walk you through EcomAgent, an AI-powered voice customer service agent that connects directly to a real e-commerce store and answers product questions through natural conversation. Unlike basic chatbots, this project shows how to integrate voice AI, real-time product search, and a 3D avatar into a fully functional customer service system.

What You Will See in This Video

Real-time voice-to-voice interaction with AI (Deepgram STT and OpenAI TTS)

Shopify product search via MCP and Zapier tools

3D avatar presence with BitHuman

LiveKit integration for professional-grade voice communication

End-to-end customer service workflow demo

Tech Stack

LiveKit Agents: voice AI framework

GPT-4o: natural conversation

MCP Protocol: universal tool integration

Zapier MCP Server: external service connector

Next.js: frontend

BitHuman: 3D avatar rendering

Deepgram: speech-to-text

OpenAI TTS: voice synthesis

Real-World Application

Built for GymFit Apparel, this AI agent can instantly answer questions like:
"Do you have blue workout leggings?"
"What is the price of running shoes?"

It searches the actual Shopify inventory and responds with live, accurate product information just like a real customer service rep.

Laravel is an incredible and mature PHP framework that has sky-rocketed in popularity since its initial introduction back in 2012. I'm happy to say that I've been a user and advocate for the framework since the beginning. I'd love to show you the ropes if you're willing! Together, we'll review each piece of the framework, and wrap up by building a Job Board platform where users can post and apply to job listings. Ready to hit the road?

Enjoy this full 8 hours course to start your journey with Laravel!

In this video, we explain how APIs work. APIs enable different applications to communicate with each other using requests and responses. They enable the seamless integration of different systems, functionalities, and services.
Non-technical companies can benefit from APIs in the same way as technical companies. Web APIs deliver client requests and return responses via either JSON or XML over the internet.
