Validate Schema API

What it does

Schema Validator checks a webpage for structured data and returns the markup it finds, along with a validation summary. Send a single url in the request body and get back the page URL plus structured signals you can inspect in your own tooling.

The response can include json_ld, microdata, meta_tags, open_graph, and twitter_card, so you can compare different metadata formats without scraping the page twice. The summary object gives you counts and health indicators such as warnings, critical_errors, types_found, total_entities, overall_score, and rich_results_eligible.

Use Schema Validator when you need to audit a marketing page, check whether product pages expose the right schema types, or spot structured-data issues before they affect search appearance. It is a fit for SEO checks, content QA, and automated page audits where you only need the validated metadata and a concise result set.

The service only accepts an HTTP or HTTPS webpage URL, and the output is focused on what was discovered on that page rather than a broad crawl or a full document parse.
