WhatIsMyIP.com (WIMI) is a simple web service and HTTP API that can be integrated into custom web accessible applications. The WIMI can be implemented to return a user IP address along with performing other domain related functions. Developers can send HTTP requests to perform a proxy check, perform a WHOIS IP lookup, check a domain to see if it has been blacklisted, lookup a host name, check HTTP server headers, and perform a user agent check. Each tool available for use comes well documented. The API can handle 55 queries at a speed of .337 seconds. JSON, CSV, and XML are all supported as output formats.
