## 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 url-metadata-extractor-68e6398e -d '<json body>'
```

Example prompt: Can you pull the metadata for https://stripe.com — I need the page title, description, OpenGraph image, and canonical URL so I can see how it appears when shared on social media?

## When to prefer this

Choose this endpoint when you need quick, structured extraction of standard web page metadata (title, description, OG tags, Twitter cards, favicon, canonical) without running a full browser. Ideal for link preview generation, bookmark enrichment, SEO auditing, and social share validation. Prefer this over a full headless browser crawl when the metadata is in static HTML and you don't need page content or rendered DOM.

## Known failure modes

- URL is unreachable or returns non-200 status — extraction fails with an error
- Page uses heavy JavaScript rendering — metadata in dynamically injected tags may not be captured
- No OpenGraph or Twitter card tags present — those fields return null or empty
- Malformed or invalid URL input — request rejected with validation error
- Target server blocks scraping bots — request may time out or return no content
