postmanlabs/httpbin ? reverse-engineered prompt

Build me a small web service like httpbin, something I can run locally and use to test HTTP requests and responses.

I want it to be easy to start with Docker, and it should expose a simple site that lets me send requests and see back useful details like headers, query params, body, method, and status codes. It should behave like a friendly request echo service, so I can use it while developing or debugging APIs.

Please make it feel polished enough to run as a real public demo too, with clear default routes and sensible responses. If you need to check current docs or examples online while building it, go ahead. Also include whatever setup is needed so I can run it with one command and test it right away.
