## About

## What it does
Keyword Clusters takes an article URL and groups the article's terms into topical clusters. Send a URL, and you get back the source URL, a primary_topic, an array of clusters, and a related_keywords list.

Use the clusters to see which themes dominate a page without manually reading through every mention. Each cluster includes a topic label and the keywords grouped under it, which makes it easier to map content to search intent, build topic briefs, or identify gaps in an article set.

Keyword Clusters is a fit for SEO workflows, content analysis, and editorial research. If you're auditing a page, planning internal links, or comparing how one article covers a subject versus another, the response gives you a compact structured summary you can feed into downstream tools.

Because the input is just a URL, it is easy to slot into crawlers, content pipelines, and CMS enrichment jobs. The output stays focused on topic-level grouping, so you can use it as-is or combine it with your own ranking, tagging, or reporting logic.
