## About

## What it does
Unified Classification predicts labels across one or more tiers from a URL, text, title, domain, or keywords. Send the content you want classified and get back scored label candidates for each requested tier.

Use Unified Classification when you need to route articles, sort product pages, organize support content, or apply a taxonomy consistently across a large dataset. You can ask for the top predictions overall with `top_k`, or narrow the request by passing specific `tiers` such as `tier1` and `tier2`.

The response returns a `tiers` object. Each tier maps to an array of label objects, and each object includes a `label` and a numeric `score`. That makes it easy to rank results, choose the best match, or display multiple classification options in your own app.

This API is a fit for content tagging, category assignment, and automated triage where you need structured classification results from a single request.
