+# 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](https://github.com/Janady13/aio-surfaces) — the toolkit that generates the Schema.org @graph from a typed site config
+- [llms.txt generator](https://huggingface.co/spaces/Janady07/llms-txt-generator) — drafts a spec-compliant llms.txt from any URL
