> By definition, API Client is a devtool that makes it easier for devs (& co.) to design, test, document, and debug APIs. If it's confusing, we can take it to Postman, but it's an industry standard, been that way for a long while.

That's not the definition of "API client" I'm familiar with. In fact it feels like a very specific definition of "API client" - which is a broad term that I am familiar with.

(Why does it sometimes feel like I am not getting the memos that everyone else is getting? It's like when a new job description for an old job suddenly appears and everyone pretends that what it's always been called!)
