How this service works
Call when an agent needs JSON-LD @type BreadcrumbList extracted from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld-breadcrumb first.
Output
Returns the extracted JSON-LD @type BreadcrumbList object parsed from the target page, containing the ordered list of breadcrumb items with their names and URLs representing the page's navigation hierarchy as structured schema.org data.
Example use cases
SEO audit breadcrumb markup
“Pull the JSON-LD BreadcrumbList from https://shop.acme.com/electronics/laptops/gaming so I can verify the breadcrumb structured data is correct for our SEO audit.”
Breadcrumb extraction from raw HTML
“I have the HTML source of a product page — can you extract the JSON-LD BreadcrumbList from it so I can see the navigation hierarchy without fetching the URL live?”
Competitor breadcrumb structure analysis
“Grab the JSON-LD breadcrumb structured data from https://www.competitor.com/blog/category/tutorials so I can compare how they structure their site hierarchy in schema.org markup.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-jsonld-breadcrumb?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract specifically JSON-LD @type BreadcrumbList structured data from a page's embedded schema.org markup, rather than scraping visible HTML breadcrumb navigation elements. Prefer the free sandbox endpoint (/v1/sandbox/profile-jsonld-breadcrumb) for testing before paying $0.005 USDC per call. Choose this over general-purpose scrapers when you specifically need machine-readable breadcrumb structured data for SEO analysis, site hierarchy mapping, or schema.org validation.
Side effects
- URL is not publicly accessible or requires authentication — returns an error indicating the page could not be fetched
- No JSON-LD BreadcrumbList present on the page — returns empty or null result
- HTML input exceeds 200,000 character limit — returns a validation error
- URL exceeds 2048 character limit — returns a validation error
- SSRF-blocked URL (private IP ranges, localhost) — rejected for security
- Malformed HTML with no parseable structured data — may return empty result
