if i had the time, I would have something setup.
its a great idea that some companies allow the use of API's and I think this is the future for most affiliates that earn their income through sign-ups.
However, most people have no clue and likewise, some programs don't either
Why spend all the time and effort to only allow someone to post through your system? Why not create that in XML instead? If you have an API, or anyone for that matter, then as a user I expect to have a lot of features available to me
