Anyone have any idea how I might go about this? Having a pretty hard time finding information online. Best I found is the curbit it gem but I can only think of how to implement that application-wise.

Often rate-limiting is applied at a reverse proxy, API gateway, or load balancer before the request reaches the API, so that it can be applied to all requests arriving at a cluster of servers. By handling this at a proxy server, you also avoid excess load being generated on your application servers.
Those limits were put in place to ensure public safety. APIs use a similar criterion, called a "rate limit," to ensure the safety of the API's consumers and the API itself. They can protect you against slow performance and denial-of-service (DoS) attacks, allow for scalability, and improve the overall user experience.
It can be handled by: 1) webserver 2) rack-application. All depend on what you need. We use built-in nginx functionality to limit API requests:
limit_req_zone $binary_remote_addr zone=one:10m rate=5r/s;
limit_req zone=one burst=2;
The another solution is rack-throttle.
This is Rack middleware that provides logic for rate-limiting incoming HTTP requests to Rack applications. You can use Rack::Throttle with any Ruby web framework based on Rack, including with Ruby on Rails 3.0 and with Sinatra.
