Just like there is a movement to make more websites (and more of websites) from pre-rendered static files (Jamstack), so to might we consider moving content-based APIs to be static. Sean C Davis:
A static API is simply a collection of flat JSON files that live on a content delivery network (CDN). It doesn’t perform any action other than delivering content (static JSON files) to the requesting user.
But that doesn’t mean a static API is simple. And every file doesn’t have to be manually generated or updated. A static API can still use a database and it can still pull data from external services. In other words, it can be dynamically generated, but it is statically delivered.
The use cases are probably somewhat limited, but I still like it. In a sense, all RSS feeds (or, more directly, JSON feeds) could be done this way, and many are.
