Getting Started with Codex (OpenAI Codex Tutorial #2)

All Episodes 👉    • OpenAI Codex Full Course: AI Coding Agent ...   In this 2nd episode of the OpenAI Codex Tutorial, we build a real Python backend with Codex as a true AI coding agent in a live coding workflow. You’ll create a FastAPI spinning wheel randomizer API, design a POST /api/pick-winner endpoint, generate and refine backend code with Codex, write automated tests with pytest, set up the project with uv, and take the code from idea to GitHub — perfect for developers learning OpenAI Codex, agentic coding workflows, FastAPI projects, REST API design, AI-powered coding, and modern Python backend development.
