PayAgent-ai

This is the final look for agent and work.

💡 Inspiration

Modern e-commerce platforms often require users to manually browse products and go through tedious multi-step checkout forms. With the rise of Agentic AI, we wanted to bridge conversational intelligence and real-world financial transactions. PayAgent AI was built to provide an autonomous shopping and payment assistant powered by the PayPal Developer Platform and intelligent intent routing.

🚀 What it does

PayAgent AI acts as an autonomous commerce agent. Users can chat with the AI assistant in natural language (asking for items like wireless earbuds, keyboards, or smartphones). The AI agent instantly analyzes simulated marketplace catalogs (Amazon / Flipkart), displays a rich visual preview card with high-resolution imagery, and directly integrates with the PayPal Orders API (Sandbox) to generate instant, secure checkout links.

🛠️ How we built it

Frontend: Built with Next.js 14, React, and Tailwind CSS for a futuristic, dark-themed responsive UI.
Backend: Powered by Python (FastAPI) handling agent intent matching and secure REST communication with PayPal.
Payments: Integrated PayPal REST APIs using OAuth2 client credentials grant and the /v2/checkout/orders endpoint for sandbox checkout redirection.
