Domain APIsLearn more about the API formats and data types we provide
Our website URL categorization API is one of the most extensive in the industry. We categorize billions of domains by leveraging advanced machine learning and artificial intelligence. Whereas our competitors often take weeks to identify threats or categorize domains, we are able to do so in real-time – ensuring you can trust our data to always be up to date. In addition to being able to categorize domains or identify threats in real-time, our artificial intelligence also supports over one dozen of the most popular languages.
The domain categorization API supports the industry standard IAB contextual taxonomy, allowing you to retrieve categories for an entire website, IP address, or a specific URL. You can accurately identify the main topics of content with more than dozens of top-level categories which can be used for services such as targeted advertising, content filtering, and security devices. In addition to supporting the IAB taxonomy, our API enriches it even further to a total of 390 categories, with detailed categories (Tier-3) for content specific to: Gambling, Weapons, Social Networks, Proxies/VPNs/Web Filter Avoidance, Streaming Media, and more.
