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.
pip installed the SDK and it just worked, endpoints responded instantly with clean JSON. Honestly didn't expect the OTP ingestion to feel this snappy for the price point.
