This project has a node/mongo server with the API written for it. There are two modules that need to be finished up quickly. One of them is about 3/4 of the way done (by me) and should be able to be replicated (for the most part) for the second widget.
There shouldn't be any problems with the API but you should have the ability to tweak it if needed.
Should not involve a lot of time for this initial project - with the prospect of expanding on the site in the future. Contact me for more details if more are needed.
