I am going to make core functionality open source on Github. Currently doing some research for market and engineering. Hoping to make the core functionality using only front-end code to keep the costs as low as possible. I will give you a heads up when I have a plan in place.
That is a nice out-of-the-box thinking. I found some plugins that could work. Unfortunately using Wordpress means that I should get a web hosting and set up a website. That even would be okay. The lack of Wordpress security and storing your API keys there is a serious problem and probably a turndown.
