BestCaptchaSolver API wrapper C#

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

Installation

Install-Package bestcaptchasolver

or

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

How to use?

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

using bestcaptchasolver;

Set access_token or username and password (legacy) for authentication

string access_token = "your_access_key";
var 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();
Console.WriteLine(string.Format("Balance: {0}", balance));

Submit image captcha

var d = new Dictionary<string, string>();
d.Add("image", "captcha.jpg");	   // file on disk, or b64 encoded string
// d.Add("is_case", "true");       // case sensitive, default: false, optional
// d.Add("is_phrase", "true");     // contains at least one space, default: false, optional
// d.Add("is_math", "true");       // math calculation captcha, default: false, optional
// d.Add("alphanumeric", "2");     // 1 (digits only) or 2 (letters only), default: all characters
// d.Add("minlength", "3");        // minimum length of captcha text, default: any
// d.Add("maxlength", "4");        // maximum length of captcha text, default: any
// d.Add("affiliate_id", "get it from /account");      // affiliate ID
var id = bcs.submit_image_captcha(d);			// use ID to retrieve `text`

Submit recaptcha details

For recaptcha submission there are two things that are required.

  • page_url
  • site_key
  • type (optional)
  • v3_action (optional)
  • v3_min_score (optional)
  • user_agent (optional)
  • affiliate_id (optional)
  • proxy (optional)

For more details about the parameters check /api page

var rd = new Dictionary<string, string>();
rd.Add("page_url", page_url);
rd.Add("site_key", site_key);
// rd.Add("type", "1");        // 1 - regular, 2 - invisible, 3 - v3, default: 1
// rd.Add("v3_action", "home");    // action used when solving v3 reCaptcha
// rd.Add("v3_min_score", "0.3");  // min score to target when solving v3
// rd.Add("proxy", "user:pass@191.123.43.34");     // proxy with/out authentication
// rd.Add("affiliate_id", "get it from /account");
var id = bcs.submit_recaptcha(rd);		// use ID to retrieve `gresponse`

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

Submit Geetest

  • domain
  • gt
  • challenge
var rd = new Dictionary<string, string>();
rd.Add("domain", "DOMAIN_HERE");
rd.Add("gt", "GT_HERE");
rd.Add("challenge", "CHALLENGE_HERE");
// rd.Add("affiliate_id", "get it from /account");

string id = bcs.submit_geetest(rd);		// use ID to get solution

Submit Capy

  • page_url
  • site_key
var rd = new Dictionary<string, string>();
rd.Add("page_url", "PAGE_URL_HERE");
rd.Add("site_key", "SITE_KEY_HERE");
// rd.Add("affiliate_id", "get it from /account");

string id = bcs.submit_capy(rd);		// use ID to get solution

Submit hCaptcha

  • page_url
  • site_key
var rd = new Dictionary<string, string>();
rd.Add("page_url", "PAGE_URL_HERE");
rd.Add("site_key", "SITE_KEY_HERE");
// rd.Add("affiliate_id", "get it from /account");

string id = bcs.submit_hcaptcha(rd);		// use ID to get solution

Retrieve (all captchas)

Use the retrieve method to retrieve text (image captcha), gresponse (reCAPTCHA) or solution (GeeTest and Capy)

id = bcs.submit_recaptcha(page_url, site_key);
string gresponse = "";
while (gresponse == "")
{
     gresponse = bcs.retrieve(id)["gresponse"];		// can be also `text` or `solution`
     Thread.Sleep(5000);
}

If reCAPTCHA is submitted with proxy, get proxy status

var proxy_status = bcs.retrieve(id)["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 example project in solution
