Here is our API to use our ProxyDetector.
A proxy is a communication interface in a network of computers in the form of a physical computer (e.g., server or, more rarely, personal computer). It works as an intermediary that receives requests on one side and then connects to the other side using its own address. If the proxy is used as a network component, on the one hand the actual address of a communication partner remains hidden from the other communication partner, which creates a certain anonymity. On the other hand, as a (possible) link between different networks, it can realize a connection between communication partners even if their addresses are incompatible with each other and a direct connection is not possible.
We get database entries by your help, by resolving IP addresses and their proxy levels. These are automatically entered into our system. We use several API's to better detect if it is a real proxy or rather a private proxy.
