BestCaptchaSolver Java API wrapper

bestcaptchasolverapi is a super easy to use bypass captcha Java API wrapper for bestcaptchasolver.com captcha service

Installation

git clone https://github.com/bestcaptchasolver/bestcaptchasolver-java

Dependencies

org.apache.httpcomponents:httpclient
org.json:json

How to use?

Simply import the library, set the auth details and start using the captcha service:

import com.bestcaptchasolver.BestCaptchaSolverAPI;

Set access_token or username and password (legacy) for authentication

String access_token = "your_access_key";
BestCaptchaSolverAPI bcs = new BestCaptchaSolverAPI(access_token);

Once you've set your authentication details, you can start using the API

Get balance

String balance = bcs.account_balance();
System.out.println(String.Format("Balance: %s", balance));

Submit image captcha

Map<String, String> d = new HashMap<String, String>();
d.put("image", "/home/me/Desktop/captcha.png");     // give it an ABSOLUTE path or b64encoded string
// d.put("is_case", "true");        // if case sensitive set to true, default: false, optional
// d.put("is_phrase", "true");      // if phrase, set to true, default: false, optional
// d.put("is_math", "true");        // true if captcha is math, default: false, optional
// d.put("alphanumeric", "1");      // 1 (digits only) or 2 (letters only), default: all characters, optional
// d.put("minlength", "2");         // minimum length of captcha text, default: any, optional
// d.put("maxlength", "4");         // maximum length of captcha text, default: any, optional
// d.put("affiliate_id", "your_affiliate_id");      // get it from /account
int id = bcs.submit_image_captcha(d);     // works with 2nd parameter as well, case sensitivty

Once you have the captchaID, you can check for it's completion

String image_text = "";
while(image_text.equals(""))
{
    image_text = bcs.retrieve(id).getString("text");
    Thread.sleep(2000);
}

Submit recaptcha details

For recaptcha submission there are two things that are required and some that are optional

  • page_url
  • site_key
  • type (optional, defaults to 1 if not given)
    • 1 - v2
    • 2 - invisible
    • 3 - v3
    • 4 - enterprise v2
    • 5 - enterprise v3
  • v3_action (optional)
  • v3_min_score (optional)
  • domain (optional)
  • data_s (optional)
  • cookie_input (optional)
  • user_agent (optional)
  • affiliate_id (optional)
  • proxy (optional)

For more details about the parameters check /api page

Map<String,String> rd = new HashMap<String, String>();
rd.put("page_url", PAGE_URL);
rd.put("site_key", SITE_KEY);
id = bcs.submit_recaptcha(rd);     // works with proxy as well, check bottom of page file for examples

Same as before, this returns an ID which is used to regulary check for completion

rd.put("domain", "https://example.com");
rd.put("captchaid", "647f5ed2ed8acb4be36784e01556bb71");

Submit Task

  • template_name

  • user_agent (optional)
  • proxy (optional)
Map<String,String> rd = new HashMap<String, String>();
rd.put("template_name", "Login test page");

// rd.put("user_agent", "your UA");
// rd.put("proxy", "12.34.56.78:1234");
// rd.put("affiliate_id", "your_affiliate_id");      // optional, get it from /account
int id = bcs.submit_task(rd);

Task pushVariables

Update task variables while it is being solved by the worker. Useful when dealing with data / variables, of which value you don't know, only after a certain step or action of the task. For example, in websites that require 2 factor authentication code.

When the task (while running on workers machine) is getting to an action defined in the template, that requires a variable, but variable was not set with the task submission, it will wait until the variable is updated through push.

The bcs.task_push_variables(captcha_id, push_variables) method can be used as many times as it is needed.

bcs.task_push_variables(id, "{\"tfa_code\": \"3495\"}");

Retrieve response (all captchas)

String gresponse = "";
while (gresponse.equals(""))
{
     gresponse = bcs.retrieve(id).getString("gresponse");	// can be also `text` or `solution` instead of `gresponse`
     Thread.sleep(5000);
}

If reCAPTCHA is submitted with proxy, get proxy status

String proxy_status = bcs.retrieve(id).getString("proxy_status");

Set captcha bad

In case a captcha was wrongly completed, you can use the set_captcha_bad(captchaID) method like this

bcs.set_captcha_bad(45);

Examples

Compile and run the com.example package

Binary

If you don't want to compile your own library, you can check the binary folder for a compiled version. Keep in mind that this might not be the latest version with every release
