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.
- JAVA Module for 2Captcha API (captcha solver)
- Get in touch
- Join the team πͺ
- License
2captcha-java artifact is available in Maven Central
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);| 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 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 |
| 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 |
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.
When you submit any image-based captcha use can provide additional options to help 2captcha workers to solve it properly.
| 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 lenght |
| 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.
Example below shows a basic solver call example with error handling.

// network error occurred
} catch (ApiException e) {
// api respond with error
