Introduction to Website categorization API

Website categorization API is one of the most accurate website categorisation services with large number of categories supported.

You can use our API service with websites, but also on texts. URL classification accepts full-path URLs and returns real-time, live URL based website categorization.

We use two different defintions for categorizations:

- IAB Taxonomy, supporting two Tiers

- Products Taxonomy

Authentication

API requests should be sent to the URL: https://www.websitecategorizationapi.com/api/

A valud API key is needed to obtain results from our API endpoints and are available by purchasing subscription to our plans.

Our API service expects for the API key to be included in all API requests to the server, as parameter:

api_key: b4dade2ce5fb2d0b189b5f0cd

You must replace b4dade2ce5fb2d0b189b5f0cd with your own API key.
