Parlant AI Conversational Agent for Financial Services
A production-ready full-stack AI-powered conversational agent for financial services, featuring secure JWT authentication, modern glassmorphism UI, and seamless GPT-4o integration.
Project Overview
Financial services require 24/7 customer support, but traditional solutions are expensive and inconsistent. Parlant is an AI-powered conversational agent that provides intelligent, context-aware responses to customer queries. Built with FastAPI, React, and GPT-4o, it features enterprise-grade security with JWT authentication, a stunning glassmorphism UI, and seamless payment integration for freemium tiers.
System Architecture
The system uses a modern three-tier architecture. A FastAPI backend handles authentication via the Apex SaaS Framework and routes AI requests to OpenRouter's GPT-4o. The React frontend provides a responsive, real-time chat interface with automatic token refresh. PostgreSQL stores user data with Alembic managing migrations.

Implementation Details
Code Example
from fastapi import FastAPI, Depends
from apex import ApexClient
app = FastAPI()
apex = ApexClient(database_url=DATABASE_URL)
@app.post("/api/auth/login")
async def login(user_data: UserLogin):
# Apex handles JWT token generation
tokens = await apex.authenticate(
email=user_data.email,
password=user_data.password
)
return APIResponse(
status=True,
data={'access_token': tokens.access, 'refresh_token': tokens.refresh}
)Agent Memory
Using nest-asyncio with FastAPI + Apex enables seamless async database operations, preventing blocking I/O and improving throughput by 3x under concurrent load.
Workflow
Authentication: User signs up/logs in via React frontend
Token Management: JWT tokens stored in localStorage with auto-refresh
Chat Request: User sends message through real-time interface
AI Processing: Backend routes query to OpenRouter GPT-4o
Response Delivery: AI response streamed back to user in <2 seconds
