The Validator API allows you to check the validity of semantic markup for a single page or an entire website, as well as extract structured data from documents.
The API processes:
- semantic markup: microformats, microdata, RDFa, and JSON-LD
- vocabularies: Schema.org, OpenGraph, and others
The validator accepts a URL or the HTML code of a page. The response is returned in JSON format.
API requests can be sent automatically or manually.
To access the Structured Data Validator API, you need a key. You can get a free API key in the Developer's Dashboard.
