A domain and IP reputation API with 15 bulk queries per second

Instantly audit your or someone else’s domain or IP address with Domain Reputation API. The tool uses hundreds of parameters to calculate reputation scores.

Get started

50 free requests monthly. No credit card required.

Each resulting reputation score is based on:

  • The website content and its relation to other domains and host configuration

  • Whether or not the domain is deemed dangerous in numerous malware data feeds all over the Internet

  • The domain’s Secure Sockets Layer (SSL) certificates, connection, and configuration

  • The domain’s mail exchanger (MX) record configuration and corresponding mail servers

  • The domain's WHOIS record

  • The domain’s nameserver configuration

  • The domain’s IP address infrastructure

  • A reverse IP address lookup

Benefits

  • An accurate estimation considering hundreds of parameters

    The resulting risk score will range between 0 (high risk) and 100 (low risk). This approach helps users identify malicious domains before getting involved with them.

  • Forewarned is forearmed

    Domains are estimated right upon their registration. Block access to untrustworthy domains before they can harm you. Figure out what type of risk a dubious domain may present.

  • Instant risk assessment

    We provide a quick-response domain reputation API that can be easily integrated into your business practices. This is a precise and up-to-date service that aims to help your organization.

Practical uses

  • Enterprise-grade security

    In an era when complex attacks make millions of dollars’ worth of data pour into unknown domains, companies need more stringent controls and enhanced automated systems to monitor their traffic. A prognostic API that assesses domain reputation can protect you from potentially dangerous domains.

  • Forensic investigations

    Reputation scores given to domains, URLs, and IP addresses allow individuals or automatic security systems to decide whether to deny, allow, or conditionally resolve a connection, depending on its type. In investigations, this helps one look into areas that are most likely to be suspicious.

  • E-commerce and online banking

    Banks, payment processors, and many e-commerce systems conduct automatic transactions from domain to domain. Such businesses will take a huge interest in monitoring potentially hazardous domains to fend off mishaps and secure themselves against losses.

  • SEO and digital marketing

    Identify key points when conducting online advertising campaigns and optimize your marketing and SEO costs. Improve your organic visibility with a well-formed backlink array.

  • Registrar and domain investment

    Users can continuously monitor web resources. They also get the best business opportunities and prevent possible financial losses.

  • Telecommunications, Internet, and streaming service provision

    Filter content by domain rating for certain user groups, parental control, and compliance with specific laws and regulations. Track suspicious sources and prevent potential harm to users.
