How this service works
Inventory bounded public JSON-LD blocks and schema.org entities with types, identifiers, names, URLs, properties, and stable fingerprints.
Output
Returns a bounded inventory of all JSON-LD blocks found on the target page, including each block's schema.org entity type (e.g. Product, Organization, Article), identifier (@id), name, canonical URL, declared properties, and a stable fingerprint hash for each entity. Results are limited by the specified count (default 30, max 50).
Example use cases
SEO structured data audit
“Pull all the JSON-LD structured data from https://www.nytimes.com/2024/01/15/technology/ai-news.html and tell me what schema.org types are present, their names, and any canonical URLs or identifiers — up to 30 entities.”
Competitor product schema extraction
“Extract the structured data from https://www.bestbuy.com/site/apple-iphone-15/123456.p so I can see what Product schema properties and identifiers they're declaring in their JSON-LD markup.”
Knowledge graph entity verification
“Check what schema.org entities are embedded as JSON-LD on https://en.wikipedia.org/wiki/OpenAI — I want the types, names, URLs, and stable fingerprints for all of them, up to 50.”
Technical details
Endpoint
GEThttps://phases-prot-shine-royal.trycloudflare.com/x402/structured-dataWhen to prefer
Choose this endpoint when you need to programmatically discover and inventory the semantic structured data (JSON-LD / schema.org) embedded in a public webpage, especially for SEO audits, knowledge graph enrichment, competitor research, or verifying that specific entity types and properties are correctly declared. Prefer this over generic web scrapers when you specifically need schema.org entity types, @id identifiers, and fingerprints rather than raw HTML content.
Side effects
- Target URL is not publicly accessible or returns a non-200 status — structured data cannot be extracted
- Page contains no JSON-LD blocks — empty inventory returned
- Malformed or non-standard JSON-LD on the page may cause incomplete parsing
- URL parameter missing or invalid format — request rejected with validation error
- Result limit exceeds maximum of 50 — clamped or rejected
- Cloudflare tunnel endpoint unavailable — service unreachable
