Webflow currently supports Adobe Fonts, but services from Monotype — MyFonts and Fonts.com — and other webfont services like cloud.typography are used more and more. For those of us that want to run our agency website or have clients that pay for bespoke fonts, we're left at a disadvantage from the editor side of things.

Monotype, in particular, has an API that could be used and authenticated against to utilize web projects.
