## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability breadcrumblist-json-ld-extractor-88ba8fca -d '<json body>'
```

Example prompt: Can you extract the JSON-LD BreadcrumbList structured data from https://example.com/products/shoes/running — I need the full breadcrumb hierarchy as structured JSON-LD.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
