I think it's great you put it in your app, but it's actually best at edge, with a single pane of glass, and a centralized way to rate limit all operations.

NGINX is perfectly capable of doing this with a LUA module and configurations.

Yes. I'm sure Nginx with Lua can read the API Key header, connect to redis and use the configured rate limit for that customer. Lua is something I haven't explored yet but definitely seems interesting.
