I found gelato too complex when dealing with 2-5 methods only but I understand that the tools are build for larger teams. It's great to get hosted documentation up and running fast and code snippets for various languages to get started.

Have a look at https://apiblueprint.org/tools.html which covers mocking APIs, converting to https://www.getpostman.com/, validation inside IDEs and generating HTML for self-hosting.

http://documentation.js.org/ is relatively new and seems to target nodejs primarily.
