Scite.ai
A citation-analysis service that classifies roughly 1.6 billion citations by whether they support, contrast with, or merely mention a claim. You reach a paper's citation report through deep links to its website. The API is enterprise-priced, so access is link-based — helpful when you want to know not just who cited a paper but how.
