Isn't there already the OPTIONS verb which does the same thing as a possible HELP method?
>The HTTP OPTIONS method requests permitted communication options for a given URL or server. A client can specify a URL with this method, or an asterisk (*) to refer to the entire server.
Yes, good point, OPTIONS would probably cover this use case. Anybody know of a framework (such as rails, phoenix, laravel, etc) that offers that? would be super interesting
