At The Markup, we build our own datasets, a lot. It’s one of the core tenets of our newsroom, and how we test our hypothesis-driven journalism.One way we do that is by finding and using undocumented APIs (or application program interfaces), which are hidden in plain sight. These APIs run behind the scenes on websites and do things that are so mundane that most people just take them for granted. Autocompleting search queries, scrolling infinitely, and filtering pages after you press a button in the user interface are all usually powered by undocumented APIs.
