Installation

Add this line to your application's Gemfile:

gem 'ruby-2captcha'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruby-2captcha

Configuration

To use the api2captcha gem, you'll need to import the module and create a Client instance. Here's an example:

require 'api_2captcha'

client =  Api2Captcha.new("YOUR_API_KEY")

There are a few options that can be configured using the Client instance:

client.api_key = "YOUR_API_KEY"

Client instance options

Option	Default value	Description
soft_id	4584	your software ID obtained after publishing in 2captcha sofware catalog
callback	-	URL of your web-sever that receives the captcha recognition result. The URl should be first registered in pingback settings of your account
default_timeout	120	Timeout in seconds for all captcha types except reCAPTCHA. Defines how long the module tries to get the answer from `res.php` API endpoint
polling_interval	10	Interval in seconds between requests to `res.php` API endpoint, setting values less than 5 seconds is not recommended

[!IMPORTANT] Once callback is defined for Client instance, all methods return only the captcha ID and DO NOT poll the API to get the result. The result will be sent to the callback URL.

To get the answer manually use get_result method

Solve captcha

Proxies

You can pass your proxy as an additional argument for methods: recaptcha, funcaptcha, geetest, geetest v4, keycaptcha, capy puzzle, lemin, turnstile, amazon waf, Cutcaptcha, Friendly captcha, MTCaptcha, DataDome, CyberSiARA and etc. The proxy will be forwarded to the API to solve the captcha.

We have our own proxies that we can offer you. Buy residential proxies for avoid restrictions and blocks. Quick start.

Example solving reCAPTCHA V2 using proxy:

result = client.recaptcha_v2({
  googlekey: '6Le-wvkSVVABCPBMRTvw0Q4Muexq1bi0DJwx_mJ-',
  pageurl: 'https://mysite.com/page/with/recaptcha_v2',
  invisible: 1,
  proxytype: "https",
  proxy: "proxyuser:[email protected]:3128"
})

Error handling

In case of an error, the captcha solver throws an exception. It's important to properly handle these cases. We recommend using begin rescue to handle exceptions.

  begin
  result = client.text('If tomorrow is Saturday, what day is today?')
  rescue Api2Captcha::ValidationException => e
    # invalid parameters passed
    puts(e)
  rescue Api2Captcha::NetworkException => e
    # network error occurred
    puts(e)
  rescue Api2Captcha::ApiException => e
    # api respond with error
    puts(e)
  rescue Api2Captcha::TimeoutException => e
    # captcha is not solved so far
    puts(e)
  end
