Global API Telecom Testing experience
Trigger real mobile calls, SMS, and app interactions worldwide. SignalVerify API provides rich artifacts, video evidence, and network insights across 149+ countries.
Automated Global Testing
Trigger high-volume, automated tests across our distributed network of real-life probes in over 144 countries. This eliminates the need for manual intervention, allowing you to validate thousands of global destinations simultaneously to ensure consistent performance across hundreds of local Mobile Network Operators (MNOs).
Real-Time Reputation Monitoring
Programmatically retrieve data on how your numbers are being flagged by major spam filters and third-party apps like Truecaller or Hiya. The API provides immediate feedback on CLI reputation and spam labeling, allowing you to rotate numbers or adjust routing before your answer rates drop.
Visual Evidence Delivery
Automatically pull definitive proof of delivery via API-driven screenshots from real devices. This feature allows your system to capture exactly how your calls, SMS, or OTT messages (WhatsApp, Viber, Telegram) appear to the end user, providing visual verification of brand identity and sender names.
NOC & CRM Workflow Integration
Directly inject validation data into your existing monitoring stacks, routing engines, or customer management systems. By integrating our API, your team can set up automated alerts for delivery failures, route quality issues, or "mislabelled" status, enabling proactive risk mitigation and immediate route optimization.
Direct-to-Device (D2D) Field Validation
Access our specialized testing layer for satellite-to-handset connectivity, bridging the gap between protocol compliance and commercial readiness. The API can trigger scenarios that validate "Cold Boot" registration, inter-satellite handover dynamics at 27,000 km/h, and session integrity across 500km–700km orbits.
Dynamic Route Validation
Integrate SignalVerify directly into your least-cost routing (LCR) or quality-based routing engines to validate path integrity in real-time. The API identifies "Drop Zones," "Grey Routes," and delivery failures before they impact your traffic. By programmatically detecting when a specific carrier route begins mislabeling calls or failing to deliver SMS, your system can automatically reroute traffic to a higher-quality path, ensuring 100% brand trust and message delivery.
