Get balance

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.

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.

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
    // domain: 'www.google.com',      // optional
    // 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.

    // affiliate_id: 'ID of affiliate'
}).then(function (id)) { /* use id to retrieve solution */ };

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

bestcaptchasolverapi.task_push_variables(captcha_id, {"tfa_code": "49651"})

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

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

Set captcha bad

bestcaptchasolverapi.set_captcha_bad(captcha_id);
