## 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 saylor-innovations-schema-org-extractor-fa08d841
```

Example prompt: Can you pull all the schema.org structured data from https://example.com/product/widget — I want to see what entity types they're using, the field names, and any parse errors in their JSON-LD markup?

## When to prefer this

Choose this endpoint when you need to programmatically inspect, audit, or compare schema.org/JSON-LD structured data on any public webpage — especially for SEO audits, competitive research, data enrichment pipelines, or verifying that a site's markup conforms to expected entity types. It is purpose-built to surface @graph nodes, microdata counts, and parse errors in a single call, making it more targeted than a generic HTML scraper.

## Known failure modes

- Page URL is not publicly accessible or returns a non-200 status — result may show no structured data or an error
- Page uses JavaScript-rendered schema.org data that is not present in raw HTML — entities may not be detected
- Malformed JSON-LD on the page may be captured in parse_errors array but entities may be partially or not extracted
- URL parameter missing — request will fail validation
- Page has no schema.org markup — response returns has_structured_data: false with empty items and types arrays

## How this service works

Extract schema.org JSON-LD structured data from a page - entity types, names, URLs and fields, including @graph, plus microdata count and parse errors

## Output

Returns a JSON object with the canonical URL, a boolean indicating whether structured data is present, the count of JSON-LD blocks and microdata items, an array of entity types found, a list of item objects (each with type, name, URL, description, and field names), any parse errors encountered, and the data source used for extraction.
