Is there any simple way to get a "Roblox script"-like web server scripting for something like a API endpoint, or a ready "example" one?

This might be a unique question, or it may not, but:

I need a way to make a simple “website” that would respond to HTTP requests with a set response, nothing further.

My main problem is, after some digging, there are no simple “Copy and post on cloudflare” solutions, and I know basically nothing more than roblox luau scripting, so I need either a readily-made solution, or any kind of way to have a “Roblox-script” like thing.

I tried to phrase this to the best of my abilities, but if anyone is confused on what I need, please ask.

If I understand you correctly, I believe you are looking for a webpage that would give a static response every time it is requested and no internal calculations. If this is the case, you could use GitHub Gist to create a file and then make a request to it as the raw link.

For instance, if your link is https://gist.github.com/treeben77/c2fc5a5b2002ae5ea7bca1f74e4e599b, you would add /raw on the end and then request this endpoint: https://gist.github.com/treeben77/c2fc5a5b2002ae5ea7bca1f74e4e599b/raw
