abstract = {Application Programming Interfaces (APIs) are fundamental to modern distributed software architectures, yet traditional testing approaches struggle with inefficiency, limited coverage, and high maintenance costs . This paper presents a novel AI-powered web application framework that automates RESTful API testing by integrating Retrieval-Augmented Generation (RAG) with locally deployed Large Language Models (LLMs) to dynamically generate, execute, and validate JSON test payloads . The system addresses critical limitations including manual effort, brittle scripts, and incomplete edge case detection by storing OpenAPI specifications in a vector-based knowledge base and using context-aware generation to produce diverse test scenarios covering positive, negative, and boundary conditions . Implementation leverages FastAPI backend with React.js frontend, supporting parallel execution with dependency resolution, JSON diff validation, and Broken Object Level Authorization (BOLA) security checks via Karate DSL integration . Experimental evaluation using mock APIs demonstrates 85% path coverage, 95% code-less automation, and 60-80% reduction in manual testing cycles within sub-150-second latency on standard 8GB RAM hardware . The framework employs SQLite for relational data persistence and ChromaDB for RAG embeddings, ensuring offline operation with 99% uptime and AES-256 data encryption . Results validate the approach's effectiveness in enhancing defect detection by 30-50% through intelligent scenario exploration while maintaining WCAG 2.1 AA accessibility standards . This work establishes a scalable, privacy-preserving model for AI-driven quality assurance, with future extensions targeting GraphQL support, cloud-native deployment, and self-healing test capabilities .},
