Hey thank you for the feedback! As r/ryanjkelly2 suggested, you could indeed use Postman, but I believe the easiest way is to use the already included Swagger UI, available at <base_url>/docs.

If your goal is to have a slightly more friendly UI for end users, it should be relatively easy to build something custom, using the OpenAI clients (or requests package) and something like Streamlit. Or even a notebook (you can use the OpenAI cookbook as a starting point).
