AntiCaptcha

AntiCaptcha is a Ruby API for Anti-Captcha - Anti-Captcha.com

Installation

Add this line to your application's Gemfile:

gem 'anti_captcha'

And then execute:

$ bundle

Or install it yourself as:

$ gem install anti_captcha

Usage

1. Create a client

client = AntiCaptcha.new('my_key')

2. Solve a CAPTCHA

There are two types of methods available: decode_* and decode_*!:

  • decode_* does not raise exceptions.
  • decode_*! may raise a AntiCaptcha::Error if something goes wrong.

If the solution is not available, an empty solution object will be returned.

solution = client.decode_image!(path: 'path/to/my/captcha/file')
solution.text                # CAPTCHA solution
solution.url                 # Image URL
solution.task_result.task_id # The task ID

Image CAPTCHA

You can specify file, body or body64 when decoding an image.

client.decode_image!(file: File.open('path/to/my/captcha/file', 'rb'))
client.decode_image!(body: File.open('path/to/my/captcha/file', 'rb').read)
client.decode_image!(body64: Base64.encode64(File.open('path/to/my/captcha/file', 'rb').read))

solution = client.decode_recaptcha_v2!(
  website_key:    'xyz',
  website_url:    'http://example.com/example=1',
  # proxy_type:     'http',                   # OPTIONAL
  # proxy_address:  '127.0.0.1',              # OPTIONAL
  # proxy_port:     '8080',                   # OPTIONAL

)

solution.g_recaptcha_response
"03AOPBWq_RPO2vLzyk0h8gH0cA2X4v3tpYCPZR6Y4yxKy1s3Eo7CHZRQntxrd..."

Parameters:

  • website_key: the Google website key for the reCAPTCHA.
  • website_url: the URL of the page with the reCAPTCHA challenge.
  • proxy_type: optional parameter. Proxy connection protocol.
  • proxy_address: optional parameter. The proxy address.
  • proxy_port: optional parameter. The proxy port.
  • proxy_login: optional parameter. The proxy login.
  • proxy_password: optional parameter. The proxy password.
  • user_agent: optional parameter. The user agent.

reCAPTCHA v3

solution = client.decode_recaptcha_v3!(
  website_key:   'xyz',
  website_url:   'http://example.com/example=1',
  page_action:   'myverify',
  min_score:     0.3,   # OPTIONAL
  # is_enterprise: false, # OPTIONAL
)

solution.g_recaptcha_response
"03AOPBWq_RPO2vLzyk0h8gH0cA2X4v3tpYCPZR6Y4yxKy1s3Eo7CHZRQntxrd..."

Parameters:

  • website_key: the Google website key for the reCAPTCHA.
  • website_url: the URL of the page with the reCAPTCHA challenge.
  • action: the action name used by the CAPTCHA.
  • min_score: optional parameter. The minimal score needed for the CAPTCHA resolution. Defaults to 0.3.
  • is_enterprise: optional parameter. Set to true if you are solving a reCAPTCHA v3 Enterprise. Defaults to false.

About the action parameter: in order to find out what this is, you need to inspect the JavaScript code of the website looking for a call to the grecaptcha.execute function.

// Example
grecaptcha.execute('6Lc2fhwTAAAAAGatXTzFYfvlQMI2T7B6ji8UVV_f', { action: "examples/v3scores" })

About the min_score parameter: it's strongly recommended to use a minimum score of 0.3 as higher scores are rare.

Notes

Ruby dependencies

AntiCaptcha doesn't require specific dependencies. That saves you memory and avoid conflicts with other gems.

Input image format

Any format you use in the decode_image! method (file, path, body or body64) will always be converted to a body64, which is a base64-encoded binary string. So, if you already have this format on your end, there is no need for convertions before calling the API.

Our recomendation is to never convert your image format, unless needed. Let the gem convert internally. It may save you resources (CPU, memory and IO).

Versioning

AntiCaptcha gem uses Semantic Versioning.
