CapMonster Cloud is a great service. CapMonsters AI solving mechanism for captchas is very fast and reliable. I have never had a failed captcha solve using CapMonster Cloud. Their service even works for Discord hCaptchas! And above all that, their prices are very low too: 0,80 dollars per 1000 tokens for hCaptcha. I am very satisfied with CapMonster Cloud and I will stay as a customer here.
If anyone needs a service to solve all kinds of captchas, I definitely recommend trying CapMonster Cloud!
For developers, the documentation is pretty good overall. It is understandable and explains the API very well.
