Edit 6/16/2013: It’s been a few months, and we finally ended up going with the Swagger-based documentation built into 3Scale.net. Want to see how it looks? Head over to developer.nutritionix.com.

As demand for our Nutritionix API is starting to grow rapidly, we have been working on finding an API documentation engine to meet our needs for the long-term. I was not able to find any comprehensive list of existing API documentation solutions, so I am compiling what I have found so far. Please leave feedback on your own experience in the comments.
Web API Documentation Tools
We are still exploring each solution, but I will update this post as we learn more about each option.
- Swagger – A specification and complete framework implementation for describing, producing, consuming, and visualizing RESTful web services. [Demo]
- apiary.io – Provides very quick way to get your documentation up and running, includes GitHub integration and I/O validation. – Suggested by Siyfion via Reddit.
- Docco – Docco is a quick-and-dirty, hundred-line-long, literate-programming-style documentation generator. It produces HTML that displays your comments alongside your code.
- Dexy – Flexible documentation tool that supports any language, for any API.
- Doxygen – Generate an on-line documentation browser (in HTML) and/or an off-line reference manual, and you can configure doxygen to extract the code structure from undocumented source files. Seems more technical than the other options, but a powerful option nonetheless. Suggested by gkumar007 via Reddit.
- TurnAPI – Paid service. Intelligent WIKI-editor, markdown based standards, documentation branching, sync with Git, SVN, Mercurial, clean looking themes. [Features]
- Note: As of writing I was unable to create an account at TurnAPI.
