Schema.org JSON-LD Validator

Validate a Schema.org JSON-LD block — paste it directly, or give a URL and we'll fetch all <script type="application/ld+json"> blocks from the page and check each.

Best-practice checks

• JSON parses
• @context is schema.org
• Every node has @type and @id
• Organization has ≥ 3 sameAs entries
• Person has at least one identifier (ORCID / Wikidata / Google KG MID)

Companion tools

• aio-surfaces — the toolkit that generates the Schema.org @graph from a typed site config
• llms.txt generator — drafts a spec-compliant llms.txt from any URL
