Each type returns validation_depth in the API response.
Added /llms.txt and /llms-full.txt — concise and full-length API references optimized for LLM context windows. AI tools and code assistants can now discover and understand the SchemaCheck API without scraping HTML.
The SchemaCheck MCP (Model Context Protocol) server is now available on npm. Add it to your Claude Desktop or Cursor config and AI assistants can call the validation API natively — no tool registration code required.
Article, NewsArticle, BlogPosting, Product, LocalBusiness, Organization, BreadcrumbList, WebSite, and FAQPage — each with required/recommended property validation, rich result eligibility checking, and Google deprecation warnings.
Public launch of the SchemaCheck REST API. Validate Schema.org JSON-LD structured data via GET (URL) or POST (raw JSON-LD). Returns per-property error messages, fix suggestions, rich result eligibility, and a 0–100 health score. Free plan: 100 validations/month.
