In the previous version, one could make a simple URL query in a web browser (e.g., "https://api.publicapis.org/categories") and receive JSON results. Might this be possible again with the new version?

I teach iOS app development (using SwiftUI) to middle school students. I used the example above to easily demonstrate the nature of JSON data without using a formal RESTful GET request. We then used the JSON data to build a list of categories (or indicies, in your case), with built-in navigation links to specific APIs. It was a cool way to introduce API calls by building an app containing a list of APIs. Students could then use the API app to select an API of their own choosing to build an API app of their own. The basic requirement was that the query had to be able to be made in a web browser with the results in JSON.

Thanks for your consideration.
