Validate JSON-LD structured data (Schema.org)
validate_jsonldRead-onlyIdempotent
Validate JSON-LD structured data against the Schema.org vocabulary. Accepts raw JSON-LD or an HTML snippet/page containing blocks (pass the text, not a URL: this tool never fetches anything). Returns valid true/false, error/warning/info counts, the Schema.org types found, and up to 25 issues with JSON paths, messages and did-you-mean suggestions. Read-only. Same engine as the RichProof JSON API (POST /api/validate).
