This is a simple website that simplifies (specifically enum JavaDoc pages) for end-user consumptions.
You can access the website directly here.
To use the API, you can use the following format:
https://cryptomorin.github.io/Javadocs-Simplifier/api/v1?url=...
E.g.
https://cryptomorin.github.io/Javadocs-Simplifier/api/v1?url=https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/meta/trim/TrimPattern.html
The page might not work in presense of custom JavaDocs generated pages (which is rare.)
