I'd very much like a public API with OAuth2 authentication, as I'd like to hook my own app into Furry Network. In the meantime, if you're happy with us reverse-engineering the app's internal endpoints, I can do that for now.

Depending on what language the site is written in, I'd like to offer my services in building a public-facing API. With Weasyl's announcement that they're going open source, it's my intention to assist with a similar project there, expanding their existing but limited API.
