# C++ Module for 2Captcha API (captcha solver)

The easiest way to quickly integrate [2Captcha] into your code to automate solving of any type of captcha.

Examples of API requests for different captcha types are available on the [C++ captcha solver](https://github.com/2captcha/2captcha-cpp/tree/master/examples) examples directory.

## Installation

The api code is a single header file api2captcha.hpp, just copy it to your project and include where needed. You need to provide a HTTP-client implementation, as there is no standard one in C++. A sample HTTP-client based on libcurl is in curl_http.hpp (libcurl v. 7.62 or higher required), include it if you are using libcurl.



## Configuration

`Client` instance can be created like this:

```c++

api2captcha::client_t client ("YOUR_API_KEY");

```

There are few options that can be configured:

```c++

client.set_soft_id (123);

client.set_callback ("https://your.site/result-receiver");

client.set_default_timeout (120);

client.set_recaptcha_timeout (600);

client.set_polling_interval (10);

```



### 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|

|recaptcha_timeout|600|Timeout for ReCaptcha in seconds. 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 URL* is defined for `client` instance with `set_callback`, 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](#send--getresult)



## 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_img|-|an image with hint shown to workers with the captcha|

|hint_text|-|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. You can build examples using 'make API_KEY=YOUR_API_KEY'. You can get example captchas from [2captcha demos](https://2captcha.com/demo).



### Basic example

Example below shows a basic solver call example with error handling.



```c++

api2captcha::normal_t captcha;

captcha.set_file ("path/to/captcha.jpg");

captcha.set_min_len (4);

captcha.set_max_len (20);

captcha.set_case_sensitive (true);

captcha.set_lang ("en");



try

{

    client.solve (captcha);

    printf ("Captcha solved: '%s'\n", captcha.code ().c_str ());

}

catch (std::exception & e)

{

    fprintf (stderr, "Error occurred: %s\n" + e.what ());

}

```

## Other methods



### send / get_result

These methods can be used for manual captcha submission and answer polling.



```c++

std::string captcha_id = solver.send (captcha);



std::this_thread::sleep_for (std::chrono::seconds (10));



std::string code = solver.get_result (captcha_id);

```

### balance

Use this method to get your account's balance



```c++

double balance = solver.get_balance ();

```

### report

Use this method to report good or bad captcha answer.



```c++

solver.report (captcha.id (), true); // captcha solved correctly

solver.report (captcha.id (), false); // captcha solved incorrectly

```



## Proxies

You can pass your proxy as an additional argument for methods: recaptcha, funcaptcha, geetest, hcaptcha, keycaptcha, capy puzzle, 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].



## 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.



```c++

try

{

    solver.solve (captcha);

}

catch (api2captcha::network_exception_t & e)

{

    // network error occurred

}

catch (api2captcha::api_exception_t & e)

{

    // api respond with error

}

catch (api2captcha::timeout_exception_t & e)

{

    // captcha is not solved so far

}

```
