## How to call it through Zero

```sh
zero fetch --capability milliapi-page-metadata-extractor-f3c4ffc0
```

Example prompt: Can you pull the page metadata from https://example.com — I want the title, description, canonical URL, Open Graph tags, and how many H1s and JSON-LD blocks it has?

Choose this endpoint when you need lightweight, structured metadata extraction from a single public HTTPS page without running a full browser — ideal for SEO audits, social preview checks, structured data inventories, or enriching link previews at low cost ($0.002/call via x402 micropayment).

## Known failure modes

- Non-HTTPS or non-public URL returns an error
- Page behind authentication or firewall cannot be fetched
- Timeout if the target page is slow to respond
- Malformed URL input returns a validation error
- Pages with no metadata return null values for most fields
