How this service works
Call when an agent needs JSON-LD @type WebSite extracted from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld-website first.
Output
Returns the JSON-LD object(s) with @type WebSite extracted from the page's structured data markup, including fields such as name, url, description, potentialAction, and other schema.org WebSite properties present in the source.
Example use cases
SEO audit for schema markup
“Check https://mybrand.com and pull out any JSON-LD @type WebSite structured data so I can verify the site's schema.org markup is correct.”
Competitor website metadata research
“Fetch the JSON-LD WebSite schema from https://competitor.io — I want to see what name, URL, and sitelinks they've declared in their structured data.”
Validate HTML snippet schema
“I have this raw HTML from a client's page — can you extract the JSON-LD WebSite entity from it so I can confirm their structured data is properly set up?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-jsonld-website?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the schema.org JSON-LD @type WebSite entity from a page, rather than generic metadata or other structured data types. Prefer the free sandbox endpoint (/v1/sandbox/profile-jsonld-website) when available to avoid the $0.003 USDC charge. Choose this over general HTML scrapers when your goal is structured linked data extraction rather than raw content.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page contains no JSON-LD or no @type WebSite entity — returns empty result
- HTML exceeds 200,000 character limit — request rejected
- URL blocked due to SSRF safety restrictions (private/internal IPs) — request rejected
- Malformed JSON-LD on the page — partial or no result returned
