Proxy Rotator’s Proxy Detection API can detect if an IP address is, or has ever been, related to a proxy. With a database of over 26,000,000 worldwide proxies our probability of detecting a proxy based upon the ip address is unmatched. This API is useful for many scenario’s such as reducing fraud on e-commerece sites, protecting your site from automated hacking attempts (XSS,SQLi,brute force), Prevent promotional offer abuse (multiple signups), limiting access on proxy IPs (prevent password / email changes) and many more uses!
