Schema Markup
Validate and transform structured data for rich search results
Schema Markup provides API-driven validation and transformation for structured data. It emulates Google Rich Results Test and the Schema.org Validator to review pages, visualize syntax, and verify eligibility for search enhancements. It supports JSON-LD, RDFa, and other RDF formats with clear warnings and source attribution.
Use a CLI, MCP, and REST API to automate checks in local development and CI, or explore examples in a browser playground. Integrate it into content pipelines to standardize markup and catch issues before publishing
