## About

## What it does
IAB Category Classifier predicts IAB Tier 2 topic labels from a URL, page text, title, domain, or keywords. Send one or more of those inputs, and you get a ranked list of category predictions back.

Use the `top_k` field to control how many predictions you receive, from 1 to 20. The response includes the detected `tier` and a `predictions` array, where each prediction contains a `label` and a `score`. That makes it straightforward to route content into ad categories, segment articles, or attach taxonomy labels in a CMS or analytics pipeline.

This is a good fit when you need to classify web pages, editorial content, or marketing copy into a standard ad taxonomy without hand-tagging every item. For example, you can score inbound URLs before storing them, or classify text snippets as part of a content moderation or campaign workflow.

The service accepts nullable `url`, `text`, `title`, `domain`, and `keywords` fields, so you can send whatever context you have and let the model predict from it.

## Usage

Authenticate with an ApyHub API key in the `apy-token` header.
