Is it Possible to Download Complete API Specification

Hi,
My organization uses R and I've been working on creating a package that lightly wraps Qualtrics API calls and returns the results as native R objects, adding some simple type checking and validation where possible. Rather than go through the API and implementing it by hand, page by page, I'm wondering if it is possible to download documents that detail the full API in a way that could be used to machine generate the aforementioned wrapper, preferably without writing a parser for the HTML. Does this exist, and if so where can I find it?

Thanks in advance!
