There is REST API and we can share it with trusted developers.
Current problem is that we don't store authors properly in DB.
There is no way to display author list from REST API.
Will need further development which might take significant amount of time.
From "philosophical" point of view, automated content loaders don't contribute much to community.
You download content anonymously through standalone app, play it and then can't even leave a comment, rating or review,
basically treating website as free archive/FTP server. It becomes a fast-food like service.
We think the biggest value of this website and alike is that community can interact, share ideas and opinions.
With interaction we can build stronger community. Loader makes whole experience extremely shallow.
We think people who contribute with their maps/mods/tools deserve attention and receiving a comment or a review is important to them.
Making content for Quake is our hobby, getting feedback is the biggest reward we can get.
Would be great if we could improve whole concept of loader, so everyone can benefit.
We can discuss ideas how to do it here.
If you're interested in API, show us your project and we'll contact you with details.
