SEMrush and SEO Score API both touch SEO, but they are different shapes of product. SEMrush is a Web app + API (custom plans); SEO Score API is a hosted REST API that returns a scored audit as JSON in about two seconds. This page is an honest side-by-side — including when you should pick SEMrush over us.
