https://www.readability.com/ is really amazing. I'm building a web app with content that I'd like to automatically run some resources through it and present the result in a lightbox.
There's a bookmarklet, but not much else. The API is dedicated to saving and updating things to a user's readability account, but not actually converting a page.
Is there a way run a site through the engine and return the results?
There's a few libraries that have popped up to do this, which may be what you're looking for.
I'd look into using something like that rather than trying to interact with Readability itself.
