Later I decided to turn it into a standalone API. You can use it to prevent most fake sign-ups for your own products.
It includes over 142K+ disposable domains (with an open claw agent that runs daily to identify new ones), fraud detection, typo correction, error handling, and custom rule management to fit your specific use cases.

I hope you give it a try. Cheers!
