## How to call it through Zero

```sh
zero fetch --capability microscrape-metadata-extractor-33b8fb27
```

Example prompt: Can you grab the page title, meta description, Open Graph tags, and favicon from https://stripe.com so I can build a link preview card?

## When to prefer this

Choose this endpoint when you need lightweight webpage metadata — title, description, OG tags, and favicon — without downloading full page content. Ideal for generating link preview cards, auditing SEO meta tags, or enriching URLs with social preview data. Prefer this over full-page scraping endpoints (like the Markdown extractor sibling) when you only need structured head-level metadata rather than body content.

## Known failure modes

- URL is unreachable or returns non-200 status — likely returns an error with request_id and empty fields
- Webpage has no meta tags — og object and description will be null or empty
- URL parameter missing — returns 400-style validation error
- Target page blocks scrapers via robots.txt or Cloudflare — may return empty or error response
- Invalid URL format — schema validation rejects the request

## How this service works

MicroScrape: page title, meta description, Open Graph tags, and favicon

## Output

Returns a JSON object containing the page's title string, meta description (or null), a nested og object with all Open Graph tag key-value pairs found on the page, the favicon URL (or null), the canonical URL scraped, and a request_id string for tracing.
