Prelude

Prelude is a developer-focused platform offering an intelligent SMS verification API designed to optimize message deliverability and enhance fraud protection. It uses adaptive, real-time routing powered by specialized AI to select the most efficient and reliable carrier routes based on ongoing analysis of carrier performance, geographic conditions, and fraud signals. This dynamic routing system improves the success rate of SMS verifications, ensuring high deliverability even in performance-critical environments such as fintech and SaaS applications.

Key features include multi-routing with instant fallback, which automatically switches to an alternative carrier if the primary route experiences congestion or failure, maintaining consistent message delivery. Prelude also integrates advanced fraud prevention mechanisms to protect against SMS pumping and other fraudulent activities, supporting secure and cost-effective verification flows from the ground up.

The API provides straightforward requests for sending verification codes and checking user submissions with responsive success or error feedback, facilitating seamless user authentication workflows. Prelude’s focus on performance, reliability, and security makes it suitable for large-scale social platforms and any application requiring robust user verification.

By leveraging intelligent routing, real-time optimization, and built-in fraud protection, Prelude helps developers maintain high verification success rates while minimizing costs and security risks associated with SMS-based user authentication.
