What this API returns
-
620+ IAB v3 categories
Each category comes back with a confidence score.
-
One call, the whole profile
Categories, logo, company, tech stack, and social links together.
-
URL or email
A URL goes in url. An email goes in email, and Klazify uses the domain after the @.
Frequently asked questions
It reads the page and assigns categories from the Klazify taxonomy, each with a confidence score from 0 to 1. The same response includes the logo, company profile, tech stack, and social links.
Yes. Send the address in the email field and Klazify classifies the company domain after the @. A website still goes in the url field.
Paid plans classify the full path, so an article URL is categorized from that page. Otherwise the call uses the base domain, such as example.com.
The classifier reads the text of the page, so it covers sites in nearly every widely used language, not only English.
