Generate Simple RESTful Data API

I need a lightweight, well-structured RESTful API that focuses purely on data retrieval. The goal is to expose a clean set of GET endpoints so my front-end application can pull records quickly and reliably.

Here’s what matters most to me:
• Clear, conventional routing (e.g., /items, /items/{id}).
• Solid response formatting in JSON, with proper status codes and error handling.
• Straightforward project structure so I can extend it later—feel free to use Express, FastAPI, Flask, or a comparable framework you’re comfortable with.
• A concise README that explains how to spin up the service locally, configure connection strings, and add new endpoints.

You’re free to choose tooling and language as long as it’s mainstream and easy for another developer to maintain. Once delivered, I’ll test the endpoints against a sample data store on my side; if each route returns the expected payload and passes basic error scenarios, we’re done.
