List of Domain Blacklists

Multiple Blacklists

We use multiple blacklists to help you identify malicious websites. You can use this API to know if a website or an online shopping site is safe or potentially malicious. We use public and proprietary blacklists, you can view the detection rate and the engines used.


Fraudulent Website

Spot Malicious Sites

With this Domain Blacklist API you can better identify websites that are involved in malicious activities and that may be unsafe for users. This API can help you spot scam and malware websites and thus know if a website should be blocked or not.


Sinkholed Domains

Sinkholed Domains

We have integrated 3 experimental scanning engines that can detect domains that have been sinkholed, phishing-like domains and scam-like domains. They have a low confidence but can be useful to identify unsafe domains not detected by other blacklists.


Domain TLDs

Most Abused TLDs

We included a check to detect if the domain TLD is listed within the most abused TLDs (.cf, .ga, .gdn, etc), plus you can view if the domain is listed in Alexa top 10K/100K/250K websites (useful to handle false positives in case a domain has a low detection rate).
