## 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 web-scraper-api-page-metadata-extractor-def83744 -d '<json body>'
```

Example prompt: Can you pull the metadata from https://techcrunch.com/2024/01/15/openai-news/ — I want to see the title, description, OpenGraph tags, author, published date, and any Twitter card info.

## When to prefer this

Choose this endpoint when you need lightweight, structured metadata extraction from a URL without fetching full page content — ideal for SEO audits, link preview generation, article enrichment, or social sharing previews. Prefer this over full content extraction endpoints when you only need header-level page signals (title, description, OG tags) rather than body text or structured elements.

## Known failure modes

- Invalid or malformed URL returns a 4xx error
- Non-existent or unreachable pages return a fetch error
- Pages behind authentication or paywalls may return incomplete or login-page metadata
- JavaScript-rendered pages may return empty or incomplete metadata if server-side HTML lacks the tags
- Rate limiting or bot-blocking on the target site may cause fetch failures
- Pages with no meta tags will return mostly empty/null fields

## How this service works

Extract page metadata: title, description, keywords, author, published/modified dates, canonical, language, favicon, and OpenGraph/Twitter card tags.

## Output

Returns structured metadata extracted from the target page including: title, meta description, keywords array, author, published date, last modified date, canonical URL, language code, favicon URL, and a full set of OpenGraph (og:*) and Twitter card (twitter:*) tag key-value pairs.
