Description

Most APIs have some sort of rate-limit.

This rate-limit can be per API call (for example AWS does this), or for the whole API.

It might not be reasonable to encode this in the types directly, but some way of configuring this would make sense, at least as a global rate-limit as wrapping every function is tedious boiler-plate.

Contributor guide

Research direction
Review the issue comments for prior discussions on rate limit configuration. Examine existing Servant combinators and type level DSL to understand how to implement a global rate limit wrapper. Consider open source rate limiting libraries in Haskell for integration.
