Gatekeepr

Gatekeepr is an API-based fraud prevention tool designed for developers and platform owners to block fake users effectively during sign-up processes. It analyzes email addresses, IP data, and user-agent details to detect disposable emails, automated sign-ups, and other suspicious behaviors, ensuring only legitimate users gain access to resources.

What Makes Gatekeepr Stand Out

• Multi-layered Verification: Executes over 20 distinct checks including email syntax validation, domain age, MX records, disposal inbox detection, IP geo-location and ASN, Tor exit nodes, datacenter/residential IP classification, and user-agent automation flags.
• Fast Response Time: Completes all risk assessments within 500 milliseconds, enabling near real-time decision making for accepting or blocking new users.
• Fraud Scoring System: Aggregates all checks into a single fraud score from 0 to 100, accompanied by detailed triggered rule flags to assist automated or manual review processes.
• Simple Integration: Uses a lightweight REST API accepting combinations of email, IP address, and user-agent signals without requiring external libraries or SDKs.

Use Cases

• Protect SaaS platforms and freemium services from resource abuse caused by disposable or automated sign-ups.
• Enhance user verification workflows by supplementing existing authentication systems with low-latency fraud detection.
• Filter suspicious traffic sources such as Tor nodes or data centers to reduce fraudulent account creation.

Frequently Asked Questions

What is Gatekeepr?

Gatekeepr is a fraud detection API focused on identifying and blocking fake users during platform sign-ups by analyzing key data points such as email, IP addresses, and user-agent information.

How does Gatekeepr fit into fraud prevention workflows?

It works as a pre-emptive filter to prevent fake accounts from consuming resources, providing platform owners actionable fraud scores and triggered rule flags to decide on auto-blocking or further review.

What kinds of limitations should be considered?

While Gatekeepr covers numerous verification layers, it may not detect every sophisticated fraud attempt and is most effective when combined with other security measures. Its accuracy depends on the quality of signals provided (email, IP, user-agent).

What alternatives or similar tools exist?

Gatekeepr competes with other anti-fraud or identity verification APIs that specialize in disposable email detection, IP reputation, and behavior analysis; however, Gatekeepr's multi-layer approach and unified fraud score provide comprehensive insight.
