> Yes, but most RESTful apis are backed by an OS that is file oriented. No? Most RESTful APIs are backed by databases. There's are a lot of variance there (Sql, NoSql, Cloudy Vs. Monothithic) but it isn't files. Even for file storage and delivery databases BLOB storage are often used rather than filesystem files. When all you're using a filesystem for is storing a large continuous memory-mapped blob so that you can avoid interacting with the filesystem's APIs almost entirely, you aren't exactly championing a filesystem's utility in the internet age. I'd go as far as to say that directly exposing filesystem files to the outside world is an anti-pattern (because it doesn't scale).
