What Is A Good And Free API Using JavaScript For Getting A Website Classified?

The Website Categorization API provides a content category to a website. It takes a URL and assigns it to the correct industry. There are other Company Logo and Categorizations APIs available on the internet, but Klazify appears to be the most popular and should meet all of your requirements.

Klazify’s Website Categorization analyzes a website’s content and meta tags with a machine learning (ML) engine. It uses natural language processing to collect text from the site and classify it into up to three categories (NLP).

Customers who require a local alternative for domain categorization will benefit from their offline database. Hardware/product integrations, custom applications, and internal use at an enterprise-level company are all common use cases.

Logo API

You can now take a company’s domain and obtain the company’s logo in return, thanks to improved technology. This type of software is ideal for app developers who require a large number of company logos and prefer a free or low-cost alternative to wait for their users to upload them. It’s currently a requirement for profile enrichment, and it’s widely utilized in banking and company databases.

Klazify generates a logo from any website on the fly, assuring that even the most unknown and new sites have a logo. The software allows you to get higher-quality authentic logos from the website and makes their backgrounds invisible. This enables the logos to be used on any backdrop other than white.

Klazify’s Company Logo API not only has most company logos ready and updated on a regular basis, but if you query with a domain for which they do not have the logo, their machine goes out and obtains it. This is what distinguishes it as the most dependable.

How Klazify Works

Klazify will go to the required domain name or URL, collect its content, and classify it according to an IAB V2 Standard classification taxonomy, which may be used for 1-1 personalization, marketing segmentation, online filtering, and more. As a result, the URL or domain can now be assigned to a particular category.

State Of The Art Accuracy

Their website categorization API is highly accurate, a simple lookup to a company’s URL will classify its industry within 385 possible topic categories.

Domain Processing

Klazify’s domain processing begins one of two ways:

  • New Domain Ingestion: Klazify examines the website, chasing new domains and re-indexing previously categorized domains.
  • External feeds: External data sources that are given to Klazify to process


Once a URL has been processed and passed the safety checks, it gets categorized. 

Domain Categorization

There are many topic categories to choose from, making the list comprehensive but slightly broader than other classification taxonomies.

The categorization provided by Klazify  is great for internet filtering and security applications, and the best part is that it’s free. They support practically all of the world’s languages as well as all of the domains available.

The Classification Taxonomy that Klazify uses is from the IAB, which was referenced before. IAB stands for “Interactive Advertising Bureau.” They’ve created a standard list of categories and subcategories for advertising purposes.

For example, if a publisher creates a Google Ads campaign and only wants it to appear on certain websites, Google uses the IAB categorization to determine which category a domain belongs to. This means that if publishers utilize Klazify to assess whether or not website URLs are relevant and topical for them to advertise on, the category that Klazify assigns to them is also applied to advertising websites throughout the internet.

Once Klazify has finished categorizing a domain, that domain can be assigned to several categories. Using the IAB criteria, a single website can only be classified into three categories.

The IAB has nearly 385+ possible topic categories to choose from.
