JAVA Module for 2Captcha API (captcha solver)

The easiest way to quickly integrate 2Captcha into your code to automate solving of any types of captcha. Examples of API requests for different captcha types are available on the Java captcha solver page.

Installation

2captcha-java artifact is available in Maven Central

Configuration

TwoCaptcha instance can be created like this:

TwoCaptcha solver = new TwoCaptcha('YOUR_API_KEY');

Also there are few options that can be configured:

solver.setHost("2captcha.com");
solver.setSoftId(123);
solver.setCallback("https://your.site/result-receiver");
solver.setDefaultTimeout(120);
solver.setRecaptchaTimeout(600);
solver.setPollingInterval(10);
solver.setExtendedResponse(1);

TwoCaptcha instance options

Option Default value Description
host 2captcha.com API server. You can set it to rucaptcha.com if your account is registered there
softId 4581 your software ID obtained after publishing in 2captcha software 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
defaultTimeout 120 Polling timeout in seconds for all captcha types except reCAPTCHA. Defines how long the module tries to get the answer from res.php API endpoint
recaptchaTimeout 600 Polling timeout for reCAPTCHA in seconds. Defines how long the module tries to get the answer from res.php API endpoint
pollingInterval 10 Interval in seconds between requests to res.php API endpoint, setting values less than 5 seconds is not recommended
extendedResponse 0 Json or String format response from res.php API endpoint, extendedResponse = 1 returns JSON format response. Suitable for ClickCaptcha, Canvas

Important

Once callback URL is defined for TwoCaptcha instance with setCallback, 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 getResult method

Tip

Use the extendedResponse(1) setting to obtain an extended response for the captcha. When using extendedResponse(1), the response will be presented as a JSON string. Utilizing the extended response extendedResponse(1) will be helpful when solving captchas such as ClickCaptcha.

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
minLength 0 minimal answer length
maxLength 0 maximum answer length
phrase 0 defines if the answer contains multiple words or not
caseSensitive 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
hintImg - an image with hint shown to workers with the captcha
hintText - hint or task text shown to workers with the captcha

Below you can find basic examples for every captcha type. Check out examples directory to find more examples with all available options.

Error handling

If case of an error captcha solver throws an exception. It's important to properly handle these cases. We recommend to use try catch to handle exceptions. The list of all errors can be found in the API documentation.

try {
    solver.solve(captcha);
} catch (ValidationException e) {
    // invalid parameters passed
} catch (NetworkException e) {
    // network error occurred
} catch (ApiException e) {
    // api respond with error
} catch (TimeoutException e) {
    // captcha is not solved so far
}
