## 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 scrapemole-reader-link-preview-seo-metadata-extraction-30050657
```

Example prompt: Can you fetch the link preview metadata for https://openai.com — I need the title, description, og:image, favicon, and any Twitter card info so I can render a proper preview card.

## When to prefer this

Choose this endpoint when you need structured link-preview or SEO metadata (Open Graph, Twitter Card, JSON-LD, favicon) from a URL rather than its full content. It is faster and cheaper than a full Markdown conversion when you only need metadata fields. It requires no API key or account setup and charges only $0.001 USDC per successful call via x402.

## Known failure modes

- URL is not publicly accessible (private, behind auth wall) — returns error, no charge
- URL times out or is unreachable — returns error, no charge
- URL returns non-HTML content not carrying metadata — returns partial or empty metadata fields
- Invalid URL format passed as query param — returns validation error
- Page has no Open Graph or Twitter Card tags — returns null for those fields but still returns basic title/description if present

## How this service works

Pay-per-call web reading for agents: any public page as clean Markdown, link-preview/SEO metadata (Open Graph, Twitter card, favicon, JSON-LD), RSS/Atom/JSON feeds normalized, every link on a page (internal/external, rel) and a site's XML sitemap as a URL list. USDC via x402, no accounts or API keys; failed calls are never charged.

Payments: x402 v2, scheme "exact", USDC on Base (eip155:8453). The payment is verified before the work and settled only when the response is 200. Terms: https://reader.scrapemole.workers.dev/terms

A JSON object containing the page's URL, final redirected URL, HTTP status, language, content type, page title, description, favicon URL, og:image URL, site name, canonical URL, full openGraph object, twitterCard object, and any JSON-LD structured data found on the page.
