MRXSIM
Zero-knowledge SMS activation & OTP API for developers
MRXSIM is a low-latency zero-knowledge SMS activation and OTP ingestion infrastructure built for automated verification workflows. It provides direct API endpoints and a native Python SDK (`pip install mrxsim`) for reliable OTP handling, reduced integration overhead, and scalable automation pipelines Designed for backend engineers building secure, high-frequency verification systems
Developers building automation pipelines and verification systems often run into the same bottleneck: SMS infrastructure that becomes unreliable under load.
High latency, inconsistent number availability, and limited integration options can turn a simple OTP flow into a major reliability issue.
I built MRXSIM to provide a cleaner infrastructure layer for SMS activation and OTP ingestion. It is a zero-knowledge, low-latency API designed specifically for backend services, automation workflows, and high-frequency verification pipelines.
Key design principles:
Direct API endpoints optimized for automated verification workloads.
Zero-knowledge architecture with a minimal data footprint.
Native Python SDK (pip install mrxsim) for simple backend integration.
Developer-focused interfaces designed for predictable automation flows.
If you build automation tools, backend systems, or verification pipelines, I’d appreciate your technical feedback.
Looking for real-world usage feedback, architecture critiques, and feature requests from developers working with these problems.
