Product Introduction

1. Checker is an API-based security tool designed to validate user sign-ups in real time by detecting disposable email addresses, suspicious domains, and device fingerprints (coming soon) with a response time under 200ms.
2. The core value of Checker lies in its ability to block fraudulent registrations, reduce server costs caused by fake accounts, and improve data quality by ensuring only legitimate users access services, while maintaining GDPR compliance and scalability for high-traffic environments.

Main Features

1. Pro Scrape Technology dynamically scans and updates a database of over 170,000 disposable email domains daily, ensuring detection of newly created temporary email providers to prevent fake sign-ups.
2. DomainCatch identifies suspicious registration patterns by analyzing multiple sign-up attempts linked to the same domain, flagging potential botnet attacks or coordinated fraud campaigns.
3. AWS-Backed Infrastructure guarantees sub-200ms response times for API requests, enabling real-time validation without compromising user experience, even during traffic spikes or high-volume usage.

Problems Solved

1. Checker addresses the financial and operational strain caused by fake accounts, which drain server resources, distort analytics, and exploit freemium models by flooding systems with invalid data.
2. The tool targets businesses with user registration systems, including e-commerce platforms, SaaS providers, forums, and web applications requiring membership validation.
3. Typical scenarios include blocking disposable email users from abusing free trials, preventing bot-driven sign-ups during marketing campaigns, and securing WordPress sites from spam registrations via a plugin.

Unique Advantages

1. Unlike competitors, Checker combines disposable email detection, domain reputation analysis, and upcoming device fingerprinting into a single API, offering multilayered fraud prevention without requiring multiple integrations.
2. The proprietary OmniCrawler technology autonomously discovers new temporary email providers, ensuring the database stays updated without manual intervention, which is critical for staying ahead of evolving fraud tactics.
3. Competitive advantages include seamless WordPress plugin integration for non-technical users, AWS-powered scalability for enterprises, and a 99.8% detection accuracy rate validated by user testimonials.

Frequently Asked Questions (FAQ)

1. How does Checker ensure minimal false positives during email validation? Checker employs customizable whitelists to exclude trusted domains and uses machine learning to refine detection algorithms, reducing accidental blocks of legitimate users while maintaining high accuracy.
2. Can Checker integrate with non-WordPress platforms like Shopify or custom-built systems? While currently offering a dedicated WordPress plugin, Checker’s RESTful API supports integration with any platform via developer-friendly documentation, and future plugins for Shopify and Wix are planned.
3. Is user data processed by Checker compliant with GDPR regulations? Yes, Checker operates fully within GDPR guidelines by anonymizing and encrypting all processed data, ensuring no personally identifiable information (PII) is stored beyond the validation process.
