Build a real Python backend using OpenAI Codex as a true AI coding agent in this live coding tutorial, where we create a spinning wheel randomizer API with FastAPI, design a POST /api/pick-winner endpoint, and show how to generate, refine, and test code step by step using Codex; you’ll learn agentic coding workflows, API-first backend development, project setup with uv, automated testing with pytest, and how to take your code from idea to GitHub - perfect for developers exploring AI-powered coding, OpenAI Codex tutorials, FastAPI projects, REST API design, and modern Python backend development.
