I actually wonder where this came from. It seems like a few popular Spring Boot projects started putting "rest" somewhere in the url path of every http endpoint that returns a serialized data structure in the response body rather than browser-renderable markup, but were they the first to do this? I try to just call these things an "http API" when talking about it myself, just to mean an endpoint that is intended for consumption by other applications, not by humans, but I'm not gonna fight other people using language the way it works in practice, where words just mean whatever enough people agree they mean, regardless of what the very first user of the word meant.
