Proxy detection is a service that can help you prevent fraud by catching harmful agents. It is important to find a service that provides the right information about IP addresses. Not all services are the same, and many will require manual configuration. In order to avoid mistakes, it is advisable to take the time to read the API documentation.
One of the most common methods of detecting a proxy is to use a simple block list. Many services use this technique, and it can be useful for certain scenarios. However, it is not always the best option for identifying a proxy.
A ping test can also be used to determine whether a proxy is being used. If the test is successful, it should return a value of 1. On the other hand, if the test is unsuccessful, it will return a negative value. This is because proxies often leave open ports and can change their connection details frequently.
Another way of determining if a user is using a proxy is to look at HTTP headers. The headers can tell you several useful things about a user’s connection. For example, they can tell you the IP address, the Internet Service Provider (ISP), the IP timezone, and more.
The free proxy detection API uses an algorithm to detect users who are accessing websites that proxy detection API documentation are not available to them. It can also detect fraudulent IPs, such as those who are trying to bypass digital rights management.
An API can be used to change proxy locations or exclude IPs. A good API will allow you to perform automated checks and include a simple interface. Some APIs even include a feature that allows you to rotate proxies.
You can also use an API to detect the type of device being used. For example, if you are accessing a gaming website, you might want to check if the user is a PC or a Mac. This can be done by asking politely. If the user is not using a PC, then they would likely be using a Mac.
When comparing the timestamps of a ping or HTTP header request to those of a WebRTC test, you can get a sense of whether a user is using a proxy. Similarly, you can check whether a proxy is connecting to a VPN or Tor exit node.
Alternatively, you can use the IPQS to detect Tor IP addresses. This API allows you to submit a CSV file of IP addresses and allow the system to do a real-time search. The results are usually accurate within about 25 miles of the actual user.
Finally, you can use the free proxy detection API to check the IP addresses of those who are connected to a VPN or Tor. This can be helpful if you are using a VPN to avoid content access restrictions. Also, the free API can also detect fraudulent IPs coming from a host. Using this method, you can keep your proxies safe and ensure that your subscriptions do not get compromised.
