Add this line to your application's Gemfile:

gem 'ruby-2captcha'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruby-2captcha


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 - 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

When you submit any image-based captcha use can provide additional options to help 2captcha workers to solve it properly.

Captcha options

Option Default Value Description
numeric 0 Defines if captcha contains numeric or other symbols [see more info in the API docs][post options]
min_len 0 minimal answer lenght
max_len 0 maximum answer length
phrase 0 defines if the answer contains multiple words or not
case_sensitive 0 defines if the answer is case sensitive
calc 0 defines captcha requires calculation
lang - defines the captcha language, see the [list of supported languages]
hint_image - an image with hint shown to workers with the captcha, translated into instructionsimg API parameter
hint_text - hint or task text shown to workers with the captcha

Below you can find basic examples for every captcha type, check out the code below.

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.

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