Welcome to the Q&A Forum

This is true, but interestingly you can still pull MozTrust and MozRank for URLs using the Mozscape API. To do that you need an active Moz subscription and a tool like URL Profiler. I'm not saying it's a good idea to utilise deprecated metrics, in fact the truth is quite the opposite and (as per Eli's response) I'd steer clear However, the question asked how to fetch these metrics and there are still ways to do so. It's just inadvisable
