from Hub sources can see that graphql can be used to query, also here:

ok, using google site search for docs,
look for "built from" string to reveal hash codes at the bottom
https://www.google.com/search?q=site%3Ahttps%3A%2F%2Fdocs.unity3d.com%2F6000.0+%22built+from+6000.0%22

then plug hash code into *but not all hashcodes are available as builds:
https://beta.unity3d.com/download/HASHCODE/download.html

release api *but doesn't show very latest ones (that are visible in hidden beta page)
