malhotram/ATal ? reverse-engineered prompt

Build me a simple FastAPI backend for a hackathon project.

I want a clean starter app that runs easily, has a few example API routes, and is set up in a way that makes it simple to add more features later. Please include basic request validation, sensible folder structure, and a straightforward way to test the endpoints locally. If anything is missing, make a reasonable assumption and keep it lightweight.

Use current docs online if you need to, and make sure the app is easy to run and understand without a lot of setup.
