Lemin Captcha demo

This page explains how Lemin Captcha is displayed and how Lemin Captcha verification works. In many cases Lemin Captcha hinders accessibility, frustrates users, limits access to open information, and makes testing difficult. Use Lemin Captcha solver for automatic bypass.

Lemin Captcha introduces interactive challenges that interrupt headless browsers and automated test runners. Send the challenge payloads to a solver API to handle them automatically and keep your pipelines running smoothly.

How to bypass Lemin Captcha

Open the developer console in your browser and search for a script tag that loads a script from api.leminnow.com

  <script src="https://api.leminnow.com/captcha/v1/cropped/CROPPED_3dfdd5c_d1872b526b794d83ba3b365eb15a200b/js"></script>

Extract the captcha_id value from the script src property. Find the id of div element used by Lemin. The default one is lemin-cropped-captcha, but the value can be changed by the website owner. Send the captcha to our API.

With SDK (recommended):

PHP

  $result = $solver->lemin([
        'captchaId' => 'CROPPED_3dfdd5c_d1872b526b794d83ba3b365eb15a200b',
        'apiServer' => 'api.leminnow.com',
        'url'       => 'https://solvecaptcha.com/demo/lemin',
  ]);

Python

  result = solver.lemin(captcha_id='CROPPED_3dfdd5c_d1872b526b794d83ba3b365eb15a200b',
  div_id='lemin-cropped-captcha', 
  url='https://solvecaptcha.com/demo/lemin')

Ruby

    # https://github.com/solvecaptcha/solvecaptcha-ruby
    require 'api_solvecaptcha'

    client =  ApiSolveCaptcha.new("YOUR_API_KEY")

    result = client.lemin({
        captcha_id: 'CROPPED_1abcd2f_a1234b567c890d12ef3a456bc78d901d',
        div_id: 'lemin-cropped-captcha',
        pageurl: 'https://www.site.com/page/',
        api_server: "https://api.leminnow.com/"
    })

Manually:

Make a POST request to our API endpoing https://solvecaptcha.com/in.php:

  {
    "key": "YOUR_API_KEY",
    "method": "lemin",
    "captcha_id": "CROPPED_3dfdd5c_d1872b526b794d83ba3b365eb15a200b",
    "api_server": "api.leminnow.com",
    "div_id": "lemin-cropped-captcha",
    "pageurl": "https://solvecaptcha.com/demo/lemin",
    "json": 1
  }

In the response you will receive the id of your captcha

  {
    "status": 1,
    "request": "2122988149"
  }

Wait 15-20 seconds and make a GET request to our API endpoint: https://solvecaptcha.com/res.php. If the captcha is already solved you will receive the answer:

  {
    "status":1,
    "request": {
        "answer":"0xaxcgx0xkxbsx0xuxb8x0xuxaux0xuxaax0xux9mx0x18x9cx0x18x92x0x18x8ox0x18x8ex0x18x7qx0x18x7gx0x18x76x0x18x6sx0x18x6ix0x18x68x0xux68x_?_gAAAAABkAHJ-DXKWoMr34j7Y-K5vt6rqQIMCcG0V4KdtDhYghZGq9Uhg0SJoUX_u2414Qeq_-dEet4IGxMbZE2F_agSXTF-8w9Iy07J84I5NcQ6iPbQgPz2R74S7fWws3rn3X5AdmOYb",
        "challenge_id":"578c0b7b-248f-480e-a3b0-fbe2cbfdcb8b"
      }
   }

If the captcha is not solved yet, you will receive CAPCHA_NOT_READY code in the response. Just repeat the request every 5 seconds until you receive the captcha answer. If something went wrong server will return an error code. Once you have the captcha answer, fill the hidden inputs lemin_answer and lemin_challenge_id with the corresponding values:

  document.querySelector('input[name=lemin_answer]').value = "0xaxcgx0xkxbsx0xuxb8x0xuxaux0xuxaax0xux9mx0x18x9cx0x18x92x0x18x8ox0x18x8ex0x18x7qx0x18x7gx0x18x76x0x18x6sx0x18x6ix0x18x68x0xux68x_?_gAAAAABkAHJ-DXKWoMr34j7Y-K5vt6rqQIMCcG0V4KdtDhYghZGq9Uhg0SJoUX_u2414Qeq_-dEet4IGxMbZE2F_agSXTF-8w9Iy07J84I5NcQ6iPbQgPz2R74S7fWws3rn3X5AdmOYb"
  document.querySelector('input[name=lemin_challenge_id]').value = "578c0b7b-248f-480e-a3b0-fbe2cbfdcb8b"
