## 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 unprice-json-ld-extractor-6648e8a1
```

Example prompt: Can you pull the JSON-LD structured data from https://example.com/product/123 and tell me what schema.org types and metadata it contains?

## When to prefer this

Choose this endpoint when you need to extract machine-readable schema.org/JSON-LD structured data from an arbitrary URL without setting up your own scraping infrastructure, and you want pay-per-request pricing via USDC on Base rather than a subscription. Ideal for ad-hoc structured data extraction, SEO audits, or enriching records with typed semantic metadata from live web pages.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — extraction fails with no items
- Target page contains no JSON-LD markup — returns empty items array with count 0
- Malformed JSON-LD on the target page — partial or empty results
- Payment fails via x402 — endpoint returns 402 before any fetch is attempted
- URL parameter missing — request is rejected due to schema validation

## How this service works

Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.

## Output

Returns a JSON object containing the source URL, a count of JSON-LD items found, and an array of extracted items where each item is a schema.org typed entity (e.g. WebPage, Product, Event) with its associated properties parsed from the page's embedded JSON-LD scripts.
