How to Build and Deploy a Blog-to-Audio Service Using OpenAI

Learn how to build a clean service that takes a blog URL or pasted text and produces a natural-sounding audio file. You will learn how to fetch blog content, send it to OpenAI’s audio API, save the output as an MP3 file, and serve everything through a small [FastAPI ](https://fastapi.tiangolo.com/)app. We will also build a minimal user interface and deploy it to Sevalla so that anyone can upload text and download audio without touching code.
