1. Look at the element's code at the page where you found reCAPTCHA.

2. Find a link that begins with www.google.com/recaptcha/api2/anchor or find data-sitekey parameter.
3. Copy the value of k parameter of the link (or value of data-sitekey parameter).

4. Submit a HTTP GET or POST request to our API URL: https://ocr.captchaai.com/in.php with method set to userrecaptcha and the value found on previous step as value for googlekey and full page URL as value for pageurl. Sending proxies is not obligatory ar the moment but it's recommended.

If captcha is not solved yet server will return CAPCHA_NOT_READY result. Repeat your request in 5 seconds.
If something went wrong server will return an error code.
7. Locate the element with id g-recaptcha-response and make it visible deleting display:none parameter.

Please note: sometimes content on the page is generated dynamically and you will not see this element in html source.
In such cases you have to explore javascript code that generates the content. "Inspect" option in Google Chrome can help in that.
As an alternative you can just use javascript to set the value of g-recaptcha-response field:
document.getElementById("g-recaptcha-response").innerHTML="TOKEN_FROM_captchaai";
8. An input field will appear on the page. And you just have to paste the answer token to that field and submit the form.

9. Congratulations, you've passed the recaptcha
