This exploit has already been reported to hcaptcha by me (qoft). This will probably not be working for long.

• Update hcaptcha.com to staging.hmt.ai inside your code.
• Also urlencode the sitekey in the request paramters.
• Send a request to getcaptcha and it'l return images with the type inside the url.

Speeds can be improved by changing the language of the actual solver.
