## 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 apiacre-com-web-metadata-extractor-17063406 -d '<json body>'
```

Example prompt: Can you extract the canonical URL, Open Graph tags, and other page metadata from https://example.com/some-article?

## When to prefer this

Choose this endpoint when you need structured, normalized metadata (canonical URL, Open Graph, Twitter Card, document meta) from a web page without building your own HTML parser. It is ideal for link-preview generation, SEO audits, content enrichment pipelines, and reading list apps. Prefer this over generic web scraping when you specifically need social and canonical metadata rather than full page content.

## Known failure modes

- URL is unreachable or returns a non-200 status — error indicating fetch failure
- Page uses heavy JavaScript rendering with no static metadata — incomplete or empty metadata fields returned
- Target site blocks bots or scrapers — access denied or empty response
- Malformed or non-HTML URL (e.g. PDF, image) — limited or no metadata extracted
- Missing Open Graph tags — only canonical and basic HTML meta returned

## How this service works

Extract webpage metadata from one public URL: page title, meta description, canonical URL, headings, hreflang, icons, feeds, Open Graph, Twitter Cards, and JSON-LD Schema.org types, with redirect and response provenance plus privacy-safe, publisher-asserted Organization facts with field evidence.

## Output

A structured JSON object containing canonical URL, page title, meta description, Open Graph properties (og:title, og:description, og:image, og:type, etc.), Twitter Card tags, author information, publication date, and other standard document metadata extracted from the target web page.
