## 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-meta-extraction-5c7886fa -d '<json body>'
```

Example prompt: Can you pull the metadata from https://example.com/article — I need the page title, description, and any Open Graph tags it has?

## When to prefer this

Choose this endpoint when you need lightweight, machine-readable page metadata (title, description, OG tags) from a URL without full HTML parsing or content scraping. It is well-suited for link preview generation, SEO audits, content enrichment pipelines, and social sharing workflows where structured meta fields are sufficient. Prefer it over full-page scrapers when you only need head-level metadata rather than body content.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — extraction fails with an error response
- Target page has no meta tags — returns an empty or minimal metadata object
- JavaScript-rendered pages may not expose meta tags to server-side fetching — incomplete results
- Malformed or missing input object — returns a validation or bad request error
- Rate limiting or network timeout when fetching the target URL — service error returned
