RingCaptcha is integrated with all major global and regional One-Time PIN (OTP) and SMS providers. RingCaptcha is like an OTP/SMS provider marketplace – they route your OTP and SMS notifications through the best available route because they know the best routes for each country/carrier.
You can get the competitive pricing for highly reliable delivery and no provider lock-in. RingCaptcha builds security and reliable layer on top of this OTP/SMS provider marketplace to protect you against fraud (Sybil attacks, Resource Exhaustion, Denial-of-Service), and ensure high deliverability reliability.
RingCaptcha makes it dead-simple to implement phone verification through our cut-and-paste widget and true single REST API call.
