Research (especially with AI) needs solid verification, articles, authors, journals, and retractions. Every published research article in the last 5 plus years has a DOI (Digital Object ID). I have a few tools that link page DOI's to a page that has "everything." (doilookup.com) pulls data from 20 sources, and the free PDF works slightly better than Unpaywall for medical articles (that's hard to do). Z-E-R-O tracking Z-E-R-O ads. Also, it searches ISBNs, ISSNs, Books authors. That's step 1, more to come.
