Normal Captcha is an image that contains distorted but human-readable text. To solve the captcha user has to type the text from the image.

Captcha example

Image pictures CAPTCHAs frequently interfere with development workflows — blocking automated tests, and CI pipelines. The practical solution is to outsource image recognition to a dedicated solver service exposed via an API and integrate that service into your test and deployment pipelines.

How to bypass image Captcha

Download the captcha image. Send image to our API.

With SDK (recommended):

PHP
    // https://github.com/solvercaptcha/solvecaptcha-php
    
    require(__DIR__ . '/../src/autoloader.php');

    $solver = new \SolveCaptcha\SolveCaptcha('YOUR_API_KEY');

    try {
        $result = $solver->normal('path/to/captcha.jpg');
    } catch (\Exception $e) {
        die($e->getMessage());
    }

    die('Captcha solved: ' . $result->code);
Python
    // https://github.com/solvercaptcha/solvecaptcha-python
    
    import sys
    import os

    sys.path.append(os.path.dirname(os.path.dirname(os.path.realpath(__file__))))

    from solvecaptcha import SolveCaptcha

    api_key = os.getenv('APIKEY_solvecaptcha', 'YOUR_API_KEY')

    solver = SolveCaptcha(api_key)

    try:
        result = solver.normal('path/to/captcha.jpg')

    except Exception as e:
        sys.exit(e)

    else:
        sys.exit('solved: ' + str(result))

    // https://github.com/solvercaptcha/solvecaptcha-ruby

    client =  Apisolvecaptcha.new("YOUR_API_KEY")

    result = client.normal({ image: 'path/to/captcha.jpg'})
    # OR
    result = client.normal({
      image: 'https://site-with-captcha.com/path/to/captcha.jpg'
    })

Manually:

Multipart sample form:

  <form method="post" action="https://solvecaptcha.com/in.php" enctype="multipart/form-data">
      <input type="hidden" name="method" value="post" />
        Your key:
      <input type="text" name="key" value="YOUR_APIKEY" />
        The CAPTCHA file:
      <input type="file" name="file" />
      <input type="submit" value="Upload and get the ID" />
  </form>

If everything is fine server will return the ID of your captcha:

OK|2122988149

Otherwise server will return an error code. After 15-20 seconds send GET request to get the result:

  GET https://solvecaptcha.com/res.php?key=YOUR_API_KEY&action=get&id=2122988149

If captcha is already solved server will respond with the answer token:

OK|W9H5K

If captcha is not solved yet server will return CAPCHA_NOT_READY result. Repeat your request in 5 seconds. If something went wrong server will return an error code. Paste received code into the field. Then, submit the form.
