Nginx LUA or C script to blacklist ips on cloudflare API

Hello, I have the following git project that I plan to integrate to limit requests and connections to my nginx web server : [login to view URL] My goal is to automatically blacklist the ips meeting certain rules (such as requests per second over a period of time or maximum open connections) and have a lua script that will curl the cloudflare api to blacklist them. I would use fail2ban but I consider parsing logs to be uneffective compared to Lua , which could process this in real time. I am using the X-Forwaded ip header to get the real ips behind cloudflare. I just need the script that will apply the ban rules and curl the cloudflare api based on that. The Api is very very simple . You can also refer to this project : [login to view URL] Only bids which have gone through requirements will be considered ! All I need is a simple lua script which will apply my request / rate limit rules to ban ips on cloudflare api, so budget for this project is $50.
