Content and Keyword Analysis API

What it does

Content Keyword Analyzer examines a webpage URL and returns a keyword-focused summary of the page. Send a URL, and you get back the analyzed URL plus structured content signals for search and content review.

The response includes extracted keywords with relevance scores, overall sentiment, readability details, and technical metadata such as detected language and word count. It also includes a tier field so you can see the subscription level associated with the detail returned.

Use Content Keyword Analyzer when you need to classify landing pages, check whether a page matches target search terms, or compare content quality across a set of URLs. It is useful for SEO workflows, content audits, and automated page triage where you need a quick signal from live web content.

If you are building a content pipeline, this endpoint gives you the structured data needed to rank pages, spot topical gaps, or flag pages that are hard to read before they go live.
