## 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-metadata-extractor-984e76ff
```

Example prompt: Can you pull the Open Graph metadata from https://techcrunch.com/2024/01/15/openai-announces-new-model — I need the title, description, featured image, and author?

## When to prefer this

Choose this endpoint when you need structured metadata (Open Graph, Twitter Card, HTML meta tags) from a specific URL without building a full scraper. It is ideal for generating link previews, auditing SEO tags, enriching content aggregators, or extracting article metadata like author and publish date. Prefer this over a general-purpose web scraper when only page metadata (not full body content) is needed.

## Known failure modes

- URL is unreachable or returns a non-200 status code — metadata will be absent or partial
- Webpage blocks bots or requires JavaScript rendering — metadata may be empty or incomplete
- URL is not absolute (missing http/https scheme) — request rejected with validation error
- Paywall or login-gated pages may return metadata for the gate page rather than the content
- Pages with minimal or no meta tags will return mostly empty fields

## How this service works

Fetch any URL and return parsed Open Graph / Twitter Card / standard HTML metadata: title, description, image, favicon, canonical, site name, type, author, keywords, published time.

## Output

A structured object containing all available metadata fields parsed from the target webpage: title, description, image URL, favicon URL, canonical URL, site name, Open Graph type, author, keywords array, and published time — populated only for fields present in the page's HTML.
