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.

*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.

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:

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.

The Soft Limit is a usage threshold set for your account, which is enabled by default upon account activation. It allows for controlled usage beyond the set plan limit.
