How to Check if an IP Address is a Tor Node Server in Node.JS

With the increase in online commerce and remote business dealings, the use of VPNs and other privacy-preserving technology has risen in tandem. Tor servers are one of these services; they hide the original IP Address of a user, reducing the ability to trace information back to its source. The following API will allow you to check if an IP Address is a Tor exit node server.

To run this API, our first step is to install the client software:

npm install cloudmersive-validate-api-client –save

Or, you can add this snippet to your package.json:

"dependencies": {
    "cloudmersive-validate-api-client": "^1.2.4"
  }

Then, you can call our function, IPAddressIsTorNode:

var CloudmersiveValidateApiClient = require('cloudmersive-validate-api-client');
var defaultClient = CloudmersiveValidateApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
var apiInstance = new CloudmersiveValidateApiClient.IPAddressApi();
var value = "value_example"; // String | IP address to check, e.g. \"55.55.55.55\".  The input is a string so be sure to enclose it in double-quotes.
var callback = function(error, data, response) {
  if (error) {
    console.error(error);
  } else {
    console.log('API called successfully. Returned data: ' + data);
  }
};
apiInstance.iPAddressIsTorNode(value, callback);
