## About

## 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.

## Usage

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