I put some time into it a couple years ago before my 2nd kid was born. I've always wanted to go back and work on making it a bit easier to use. One of the things I'd love to do is get rid of it being so tied to request handlers so you can use it more seamlessly in apps.
Yeah it would be great to be able to make API requests using the helper methods from outside of a request handler. As it is, it isn't that difficult to do it otherwise but it's just more code duplication.
