Doc Enhancement: Add Response samples

[dri94]

Since there is not test api for reverseApi users, it would be great to include sample success/error responses for each example in the doc. This will help users test their code without the need for a test API. Some endpoints do not follow the docs response exactly as well so it's good to know what to expect.
