Expose a .well-known URI
Describe the problem to be solved Automatic discovery of API documentation portals is not easy, even with great documentation websites, automatically downloading the up-to-date schemas is not an easy task.
Describe the solution you'd like My first idea is to use https://en.wikipedia.org/wiki/Well-known_URI
Either a /.well-known/apis.json or /.well-known/redoc.json would be enough, to get a simple list of documented APIs on the portal you're browsing, and get the list of specification files there too, to simply download the specifications.
Otherwise another URL path would be ok, a simple exampleportal.com/redoc.json would be nice
Describe alternatives you've considered None
There is a proposed spec: https://apisjson.org/format/apisjson_0.17.txt
I haven't reviewed it in depth yet.
