Production API Documentation

Welcome to the Production API documentation for RecoAgent. This section covers everything you need to know about deploying, securing, and operating the production-ready FastAPI service for enterprise RAG systems with LangGraph agents.

Overview​

The Production API is a comprehensive, enterprise-grade FastAPI application designed for production deployment of RAG (Retrieval-Augmented Generation) systems. It provides:

  • JWT Authentication & Authorization with role-based access control
  • PostgreSQL-based conversation persistence for reliable data storage
  • Comprehensive monitoring with Prometheus metrics and health checks
  • Docker containerization with security hardening
  • Rate limiting and request queueing with Redis
  • Kubernetes deployment with auto-scaling capabilities
  • Security hardening with industry best practices

Quick Start​

  1. Deployment: Follow the Deployment Guide to get started with Docker or Kubernetes
  2. Security: Review the Security Guide for security hardening and compliance
  3. Operations: Use the Runbooks for day-to-day operations and troubleshooting

Architecture​

The Production API follows a microservices architecture with:

  • FastAPI Application: High-performance async web framework
  • PostgreSQL: Reliable conversation persistence
  • Redis: Caching, rate limiting, and request queueing
  • Prometheus + Grafana: Comprehensive monitoring and alerting
  • Jaeger: Distributed tracing for request tracking
  • Nginx: Reverse proxy with SSL termination
