How this service works
Inventory bounded public JSON-LD blocks and schema.org entities with types, identifiers, names, URLs, properties, and stable fingerprints.
Output
A bounded inventory of JSON-LD structured data blocks found on the target page, including schema.org entity types (e.g. Article, Organization, Product), identifiers (@id), names, URLs, key properties, and stable fingerprints for each block. Results are capped by the specified limit (default 30, max 50).
Example use cases
SEO structured data audit
“Can you inventory all the JSON-LD structured data blocks on https://www.shopify.com — I want to see every schema.org type, identifier, and property they're using, up to 30 results.”
Competitor product schema research
“Extract the JSON-LD structured data from https://www.apple.com/iphone/ and tell me what schema.org entity types and product properties they have embedded in the page.”
Knowledge graph entity discovery
“Check https://en.wikipedia.org/wiki/Albert_Einstein for all JSON-LD entities — I want the types, names, URLs, and any stable fingerprints found in the structured data, limit to 25.”
Technical details
Endpoint
GEThttps://trinity-throw-thursday-gravity.trycloudflare.com/x402/structured-dataWhen to prefer
Choose this endpoint when you need to systematically extract and catalog schema.org / JSON-LD structured data from a specific public web page — especially for SEO audits, knowledge graph enrichment, entity discovery, or competitive research on semantic markup. It is preferable over generic scraping tools when you specifically need typed, fingerprinted schema.org entities rather than raw HTML or visible text content.
Side effects
- Page has no JSON-LD structured data — returns empty inventory
- Target URL is not publicly accessible or returns non-200 status
- URL is malformed or not a valid URI — input validation error
- Page returns JSON-LD that is malformed or unparseable — partial results or error
- Rate limiting or Cloudflare timeout on the target domain
- Result limit parameter out of range (must be 1–50)
