## 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 402utils-structured-data-extractor-32441be6 -d '<json body>'
```

Example prompt: Can you pull all the structured data from https://www.example.com/product/blue-widget — I want to see the JSON-LD objects, any schema.org types like Product or Offer, and the Open Graph tags?

## When to prefer this

Choose this endpoint when you need to reliably extract machine-readable metadata (JSON-LD, Open Graph, microdata) from any public webpage or raw HTML. Ideal for SEO audits, product data extraction, content enrichment pipelines, and verifying schema.org markup. JSON-LD extraction is the reliable path; microdata is best-effort.

## Known failure modes

- URL fails SSRF check or is private/internal — blocked with error
- HTML exceeds 5 MB limit — rejected
- Malformed JSON-LD — yields parseError entry in response rather than crashing
- URL is unreachable or returns non-200 — fetch error returned
- Page has no structured data — returns empty arrays/maps

## How this service works

Extract a page's structured data: JSON-LD (schema.org), Open Graph tags, and best-effort microdata. Returns the parsed JSON-LD objects, detected schema.org types (Product, Offer, Review, Event, Recipe, Article…), microdata items and the og:* map. Send inline {html} or a public {url} (SSRF-checked). Malformed JSON-LD yields a {parseError} entry, never a crash. Microdata is best-effort; JSON-LD is the reliable path. Max 5 MB.

## Output

Returns parsed JSON-LD objects with detected schema.org types (Product, Offer, Review, Event, Recipe, Article, etc.), microdata items (best-effort), the og:* Open Graph property map, and any parseError entries for malformed JSON-LD. Never crashes on bad input.
