Bypass image captcha and reCAPTCHA with bestcaptchasolver service, JS library

Installation
npm install bestcaptchasolver-client

or

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

Usage
Promises are used inside the library, for better code management

Simply require the module, set the auth details and start using the captcha service:

Code:

<!-- Load jQuery (dependency) -->
<script src="http://code.jquery.com/jquery-3.3.1.min.js"></script>
<!-- Load the API library -->
<script src="../lib/bestcaptchasolver.js"></script>

Set access token, before using the library
bestcaptchasolverapi.set_access_token('access token from /account');

Get balance

Code:

bestcaptchasolverapi.account_balance().then(function (balance) {
    console.log('Balance: $', balance);
})

Submit image captcha
The submission of image captcha is done by sending us the image as a b64 encoded string.

Code:

bestcaptchasolverapi.submit_captcha({
    b64image: captcha,
    // is_case: true,         // case sensitive, default: false, optional
    // is_phrase: true,       // contains at least one space, default: false, optional
    // is_math: true,         // math calculation captcha, default: false, optional
    // alphanumeric: 2,        // 1 (digits only) or 2 (letters only), default: all characters
    // minlength: 2,           // minimum length of captcha text, default: any
    // maxlength: 3,           // maximum length of captcha text, default: any
    // affiliate_id: 'ID of affiliate'       // default: None, optional
}).then(function (id)) { /* use id to retrieve text */ };

Submit reCAPTCHA
The page_url and site_key are the only requirements. There are other optional parameters though.

Code:

bestcaptchasolverapi.submit_recaptcha({
    page_url: 'PAGE_URL_HERE',
    site_key: 'SITE_KEY_HERE',
    // other parameters
    // -------------------------------------------
    // reCAPTCHA type(s) - optional, defaults to 1
    // -------------------------------------------
    // 1 - v2
    // 2 - invisible
    // 3 - v3
    // 4 - enterprise v2
    // 5 - enterprise v3
    //
    // type: '1',
    //
    // user_agent: 'Your user agent',
    // proxy: 'abc:def@12.35.56.78:4321 or 12.35.56.78:4321',
    // v3_action: '',   // v3 action
    // v3_min_score: '0.3', // if v3, score to target
    // data_s: 'recaptcha data-s parameter used in loading reCAPTCHA',
    // cookie_input: 'a=b;c=d',       // used in reCAPTCHA solving, optional
    // affiliate_id: 'ID of affiliate'       // optional
}).then(function (id)) { /* use id to retrieve response */ };

Just like the image submission method, this method also returns an ID, which is then used to get the text or gresponse.

Submit Geetest

domain
gt
challenge
api_server (optional)

Code:

bestcaptchasolverapi.submit_geetest({
    domain: 'DOMAIN_HERE',
    gt: 'GT_HERE',
    challenge: 'CHALLENGE_HERE',
    // api_server: 'GT_DOMAIN_HERE',         // optional
    // affiliate_id: 'ID of affiliate'       // optional
}).then(function (id)) { /* use id to retrieve solution */ };

Submit Capy

page_url
site_key

Code:

bestcaptchasolverapi.submit_capy({
    page_url: 'PAGE_URL_HERE',
    site_key: 'SITE_KEY_HERE',
    // affiliate_id: 'ID of affiliate'       // optional
}).then(function (id)) { /* use id to retrieve solution */ };

Submit hCaptcha

page_url
site_key

Code:

bestcaptchasolverapi.submit_hcaptcha({
    page_url: 'PAGE_URL_HERE',
    site_key: 'SITE_KEY_HERE',
    // affiliate_id: 'ID of affiliate'       // optional
}).then(function (id)) { /* use id to retrieve solution */ };

Submit FunCaptcha (Arkose Labs)

page_url
s_url
site_key

Code:

bestcaptchasolverapi.submit_funcaptcha({
    page_url: 'https://abc.com',
    s_url: 'https://api.arkoselabs.com',
    site_key: '11111111-1111-1111-1111-111111111111',
    // data: '{"x":"y"}',  // optional
    // affiliate_id: 'ID of affiliate'       // optional
}).then(function (id)) { /* use id to retrieve solution */ };

Retrieve
Retrieval is done by passing the ID, for all captchas

bestcaptchasolverapi.retrieve_captcha(id).then(function (data) { console.log(JSON.stringify(data)); });
This method returns an object, with the text attribute for image captcha or gresponse if submission was done for reCAPTCHA or solution for geetest and capy

If reCAPTCHA is submitted with proxy, get proxy status

Code:

log('Recaptcha response: ' + data.gresponse);
log('Proxy status: ' + data.proxy_status);

Set captcha bad
bestcaptchasolverapi.set_captcha_bad(captcha_id);
