API Documentation

Parameter	Description
`url` or `email`	[Required] The URL or email address to classify.
`refresh`	[Optional] `true` or `false`. Forces Klazify to fetch live, fresh data directly from the website instead of returning cached results. • Default behavior (without refresh): Klazify returns the most recent cached version of the data. This is faster and does not consume extra processing time. • With refresh=true: Klazify visits the website in real-time, re-crawls it, and returns freshly generated data. Useful when a website has recently changed and you need updated classification. • Availability: Advanced, Plus, Business, Scale, and Premium plans (monthly and yearly). • Not supported on: `/api/categorize` (All Together) and `/api/real_time_categorization` (already live by default).

POST /api/categorize

All Together (Categorization)

Returns categories, logo, social media, company, and tech stack in a single call. Ideal for testing and getting a quick overview of all available data for any domain.

Traffic Intelligence API

Traffic analytics: global rank, country rank, category rank, monthly visits, engagement metrics (bounce rate, pages/visit, time on site), traffic sources breakdown, and top countries by traffic share.

refresh parameter: Supports refresh=true. Without it, returns cached traffic data. With refresh=true, fetches the latest traffic metrics from our intelligence sources. Requires Advanced plan or above. Note: This entire endpoint is only available on Advanced plans and above.

About the Categorization

Klazify performs three types of categorizations for URLs or emails:

Klazify's Own Categories: An extensive list of 620+ custom categories. See the full list in Available Category Structures below.
IAB V1: Categorization based on IAB Content Taxonomy Version 1.
IAB V3: Categorization based on IAB Content Taxonomy Version 3 — the global standard for contextual targeting and brand safety.

The IAB V1 and V3 categorizations may or may not be present, depending on whether the specific Klazify category aligns with an IAB category.

Composition of IAB V3

IAB V3 categorization is a more advanced set of categories that contextually describes the topic or “what the content is about.” Additionally, IAB V3 includes a series of vectors that cover aspects such as content language, format, source, media type, and more. All attributes are associated with identifiers (IDs) structured as:

IAB-Unique_Category_ID-Parent_Category_ID

Example for zylalabs.com:

IAB-599 (Technology & Computing) — The site is related to Technology & Computing.
IAB-602-599 (Software and Applications / Technology & Computing) — Tier 2 child of 599.

The first ID from left to right corresponds to the parent category (Tier 1), while the second corresponds to the child (Tier 2). Up to 4 tiers can exist. More details at IAB Tech Lab.

Confidence Score

A confidence score is a number between 0 and 1. A score of 1 is likely an exact match. The higher the score, the greater the confidence in the classification response.
