## 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 pennyrail-web-page-metadata-extractor-897c035f -d '<json body>'
```

Example prompt: Can you pull the page title, description, and any Open Graph metadata from https://example.com so I can use it for a link preview card?

## When to prefer this

Choose this endpoint when you need quick, lightweight extraction of page-level metadata (title, description, OG tags) from a URL without full browser rendering. It is ideal for link preview generation, SEO audits, or enriching records with website info. Prefer this over full-page scrapers when you only need head-level metadata and want fast, low-cost results at $0.002 per call.

## Known failure modes

- URL is unreachable or returns a non-200 status — endpoint may return an error or empty metadata
- Page uses heavy JavaScript rendering — statically fetched metadata may be incomplete or missing
- URL is malformed or missing — input validation error returned
- Page blocks scrapers via robots.txt or rate limiting — metadata may be partial
- No meta tags present on page — response will contain minimal or empty fields
