Free CC Checker & Email Bounce Checker Proxy List & Security Tools
DARKXCODE is an enterprise-grade security reconnaissance and diagnostic platform uniting multi-engine website scanners, high-throughput email and bounce validators, network intelligence utilities, and Microsoft 365 credential verification into a single low-latency dashboard. Engineered for developers, penetration testers, and sysadmins, every tool exposes both a clean browser UI and a 50 req/sec JSON REST API protected by rolling-window throttling and real-time Telegram telemetry.

Under The Hood
Engineered For Strict Velocity & Reliability
A dual-lane throttling engine, millisecond sliding-window accounting, and automated Telegram operations ensure zero over-admission and deterministic execution.
Human UI Lane (10/sec)
Web browser sessions are limited to 10 list checks per rolling second with GET_LOCK serialization. Prevents UI freezes while guaranteeing immediate feedback.
High-Speed API Lane (50/sec)
Automated CLI integrations using dedicated dxx_ API keys run on a 50 list/sec ceiling with true rolling-window eviction.
Zero Password Retention
Office365 credentials stream through dynamic proxy rotation in memory. Verified credentials output to docs & UI but are never written to disk or database tables.
Predictable Billing
Simple Credits or Unlimited Access
Active subscriptions grant priority zero-deduction access. On pay-as-you-go, credits deduct only when a scan returns a definitive LIVE or DIE result.
