## 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 x402-web-tools-page-metadata-extractor-b390b0ad
```

Example prompt: Can you fetch all the metadata for https://x402.org/ — I need the title, description, Open Graph tags, canonical URL, any RSS feeds, and the JSON-LD structured data on that page?

## When to prefer this

Choose this endpoint when you need rich, structured metadata from a public web page in a single call — especially when you need Open Graph tags, JSON-LD structured data, RSS/Atom feed discovery, canonical URL, and heading outline all at once. It is ideal for link preview generation, SEO auditing, content indexing, and article metadata extraction. Prefer this over a full-page scraper when you only need metadata fields rather than body content.

## Known failure modes

- Non-HTTPS URL provided — endpoint requires https:// URLs
- Page is behind authentication or a paywall — returns incomplete or no metadata
- URL is unreachable or returns a non-200 status — extraction fails
- Page has no Open Graph tags or JSON-LD — those fields return empty arrays or null
- Dynamic JavaScript-rendered metadata may not be captured if page requires JS execution
- Malformed or missing URL query parameter — returns validation error

## How this service works

Title, description, canonical URL, language, author, published and modified dates, favicon, RSS and Atom feeds, Open Graph and Twitter card tags, JSON-LD structured data and the h1/h2 outline of a public web page.

## Output

A JSON object containing: page title, meta description, canonical URL, language code, published and modified dates, author, favicon URL, array of RSS/Atom feed URLs, Open Graph tags (image, title, description, etc.), Twitter card tags, JSON-LD structured data array, and the h1/h2 heading outline of the page.
