Binance - Binance captcha

View full price

Attention!

• CapMonster Cloud uses built-in proxies by default — their cost is already included in the service. You only need to specify your own proxies in cases where the website does not accept the token or access to the built-in services is restricted.

• If you are using a proxy with IP authorization, make sure to whitelist the address 65.21.190.34.

• Use only to log in with your account.

How to obtain websiteKey and validateId

Enable Developer Tools, go to the Network tab, activate the CAPTCHA, and look at the requests. Some of them will contain the required parameter values. For example, the parameters:

bizCode: "CMC_register", securityId: "09295759baca4d4fbeae80d9ffeaefd8"

or

bizId: "CMC_register", securityCheckResponseValidateId: "09295759baca4d4fbeae80d9ffeaefd8"

or

bizType: "login", validateId: "ff965ea6216b46f3825fa827ecaf297f"

or

bizId: "login", securityCheckResponseValidateId: "ff965ea6216b46f3825fa827ecaf297f"

The necessary parameters to solve the captcha can be obtained by executing JavaScript:

let originalBCaptcha = window.BCaptcha;
let BCaptchaData;

Object.defineProperty(window, 'BCaptcha', {
  get: function() {
    return function(args) {
      const BCaptcha = new originalBCaptcha(args);
      let BCaptchaShow = BCaptcha.__proto__.show;
      
      BCaptcha.__proto__.show = function(args) {
        BCaptchaData = args;
        return 1;
      };
      
      return BCaptcha;
    };
  }
});

Then, you can retrieve the parameters, for example, like this BCaptchaData.securityCheckResponseValidateId.
