Solving a captcha

Solving a captcha using 2captcha's api is through the in.php and res.php endpoints.
This package encapsulates the mentioned endpoints through submit and answer.
If you'd like to poll for the answer, use solve.

Default timeout: 120 seconds.
ReCAPTCHA timeout: 600 seconds.
Polling interval: 10 seconds
