How this service works
Call when an agent needs every JSON-LD block as JSON text extracted from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld first.
Output
Returns an array of JSON objects, each representing one JSON-LD block found in the page's <script type='application/ld+json'> tags, parsed from their raw JSON text form. Multiple blocks may be returned if the page contains several.
Example use cases
Extract product schema from e-commerce page
“Grab all the JSON-LD structured data from https://shop.example.com/shoes/runner-pro-x — I want to see every schema.org block they've embedded on that page.”
Audit a site's structured data markup
“I have this raw HTML from a client's homepage — can you extract all the JSON-LD blocks from it so I can check what structured data they're publishing? Here's the HTML: <html>...</html>”
Retrieve organization profile data
“Pull all the JSON-LD metadata from https://acme-corp.com/about — I'm looking for their organization and person schema markup.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-jsonld?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need ALL JSON-LD blocks from a page regardless of their @type, rather than a type-specific extractor (e.g. use the Product, Event, or Person sibling endpoints when you know the target type). Prefer this over the free sandbox /v1/sandbox/profile-jsonld endpoint when you need production reliability and paid-tier SLA. Choose this when your input is either a URL or raw HTML and you want SSRF-safe fetching handled server-side.
Side effects
- URL is not publicly reachable or times out — returns error response
- URL targets a private/internal network address (SSRF protection blocks it) — returns 403 or error
- HTML input exceeds 200,000 character limit — validation error
- No JSON-LD blocks found on the page — returns empty array
- Malformed HTML that cannot be parsed — may return empty result or partial extraction
- URL is missing or too short (minLength 8) — validation error
