Hi @Pablo 
Thanks for reaching out to the Tor Forum.
There’s no definitive or “official” list of Onion Services. However this list could provide you with a starting point for further exploration.
Some folks on GitHub provide lists of Onion Services, the current name for what was once referred to as Tor Hidden Services, whilst other GitHub users provide so-called Hidden Wiki URLs &, of course, further web searches will provide yet additional lists.
Happy trails!
