I'm looking for an API for categorized lists of public companies. Some of the examples of the lists are: IPOs 2016, Tech, Oil etc. If there's no existing API then any suggestions or ideas to automate the process are welcome.

What service or subscription do you use to stay up to date? Do you learn from services like TreeHouse, CodeSchool, EggHead.io, PluralSight, Lynda etc. I would love to hear and learn from your experiences.
