Based on a trusted public standard
Our classification taxonomy is based on the IAB V3 standard, it can be used for 1-1 personalization, marketing segmentation, online filtering and more.
Logos at your fingertips
With the same API call, you can get also any company's up-to-date logo. Extract logos on the fly on any domain, URL or IP address.
A few of Klazify's Best Features 
Smart Categorization Technology
Our Website Categorization API uses a machine learning (ML) engine to scan a website’s content and meta tags. It extracts text to classify the site and assign up to three categories aided by natural language processing (NLP).
Extract logos on the fly
One API call to get any company's up-to-date logo. Our APIs are real-time, you’ll get results even for the newest and most obscure brands with only one API call.
Social Media Links Scraper
Get the list of links of all the social media channels of a domain. Our APIs are real-time, you'll get updated social media links always.
Parked Domains Recognition
With this API you can check if a domain is actually parked and/or for sale. A parked domain is like an "under construction" domain that is "parked" and is doing nothing. However, some parked domains may show suspicious advertisements or may redirect users to third-party websites that may be unsafe.
Find Competitors or Similar Domains
With one API call you will be receiving a list of Domains of potential competitors and similar domains, based on the category and target market of a given URL.

We analyze the text from any URL and classify it into 620+ possible topic categories (our classification taxonomy is based on the IAB V3 standard).
Yes, absolutely. If you want to cancel your plan, simply go to your account and cancel on the Billing page. Upgrades, downgrades, and cancellations are immediate.
Prices are listed in USD. We accept all major debit and credit cards. Our payment system uses the latest security technology and is powered by Stripe, one of the world’s most reliable payment companies. If you have any trouble with paying by card, you can pay using PayPal.
You may request a refund for the current month if you request it within 2 hours of the transaction and only applies to the first payment we receive. We reserve the right to decline that request should you use our software within this time.
It's free to use for your first five ticket sales. Once your sixth ticket purchase comes through we will start charging the standard PAYG rate. If you would like to move to Pre pay then head to "Billing" and "Buy ticket credits".
If you are interested in our offline database, please contact [email protected] and our support team will be happy to help you.
The categories are matched by using the full path URL or the email's domain (if the input is an email).
The format of our offline database is CSV.
A base domain consists of only two of the URL elements: Domain Name and Top Level Domain (TLD). For example google.com, amazon.com, etc. For categorization purposes, if your plan doesn't support Full Path URLs, we will use the base domain content to assign an appropriate category value.
In contrast, a full path URL refers to an EXACT location (i.e. page, article, file, etc.) and allows for a highly specific analysis and categorization of web content at the specified address.
For example https://www.wsj.com/articles/how-entrepreneurs-can-get-the-most-out-of-a-business-coach-11630678676
All our paid plans support full path URL classification, so any URL will be classified based on the content of the exact location.
Yes! But it has to be for a bigger bundle than what’s available.

You will be required to downgrade your account back to the Free Plan.
Step 1: Navigate to the Subscription page, click "Downgrade" in the Free Plan section and confirm your downgrade.
Downgrades are effective immediately, your premium subscription will not remain active until the end of the current billing period.
Step 2: Once your billing period ends and your account downgrade has become effective, navigate back to the Subscription Page
and click "Upgrade" in your preferred subscription plan's section. You will now be asked to choose a new billing frequency.
Yes! It’s deleted automatically. The information is handled by Stripe or Paypal, we don’t store your credit or debit card data.
If you’re paying with a Credit /Debit card, you can find them by going to billing → billing portal-> invoices.
If you’re using paypal you have to download the Transaction Details from http://paypal.com/
If you exclusively want an offline database, we have two options:
*You can send us a CSV file with the domains you’re interested in classifying and we will return an enriched file with the desired domains classified.
*The other alternative to offline databases is a predefined file we can make with the top 5M most visited websites in those categories according to SimilarWeb web ranking (or any other filter related to SimilarWeb web ranking).
With Klazify you can categorize any mobile app using its download URL in real-time. To get it, you have to search for the Google Play Store or Apple App Store URL of the app selected
No, but you can edit it manually.
We have billions of records and if we don't have it we could get it based on your real-time request..
By default, it is 360 /minute because we want to avoid attacks or abusers, but we can expand it for you in case you need more.
Sometimes we couldn’t get data for some domains. If you could give us a list of unsuccessful domains we could double-check from our side if something is needed to improve classification algorithms.
Please send the list to [email protected] don’t worry, we don’t charge for unsuccessful calls.
Revenue info is estimated revenue and could be updated monthly if new data is available. Also, it depends on the companies you are querying, if the company is public we will update it every Q, if the company is private we try to give a range based on location and employee count changes (if some field is null, we will be null on revenue)
Yes! There is nothing wrong with parked domains, however sometimes they may pose a risk because they may display malicious advertisements that may lead to malware websites, or they may redirect users to adult or unsafe websites. This JSON API can be used in threat prevention to accurately detect parked domains or you may want to scan a list of domains to find out which one is now a parked domain.
Competitors/Similar Domains Endpoint will deliver a list of domains for companies that are related to the activity and category of a given URL. This tool is great to find potential competitors and similar domains. Finding similar domains will allow the user to make research and market analysis. For example, you can check how competitors offer their products or services, how they describe their company and more.
Klazify classifies content using AI algorithms. Therefore, if a URL is redirected to another URL, the destination URL will be classified. For example, http://facebookmail.com is redirected to http://facebook.com. In this case, the URL that will be classified based on its content is http://facebook.com, returning:
"categories":[{ "confidence": 0.91, "name": "/Online Communities/Social Networks" }]
Our system can identify and resolve specific subdomains by mapping them to their primary domain. For instance, [finance.yahoo.com](http://finance.yahoo.com/) and `mail.yahoo.com` will be recognized as subdomains of `yahoo.com`. This helps in maintaining consistency and accuracy in our domain resolution process.
