## 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 agentreader-meta-tag-extractor-90603ddf
```

Example prompt: Can you pull all the metadata from https://example.com/blog/my-post — I want the title, description, Open Graph tags, canonical URL, and any JSON-LD types so I can build a link preview card.

## When to prefer this

Choose this endpoint when you need lightweight, fast metadata extraction from a URL without needing the full page body — ideal for link previews, SEO audits, content classification, and Open Graph / Twitter card inspection. Prefer this over a full-page scraper or article extractor when you only need head-level metadata, structured data types, and headings rather than the main article content.

## Known failure modes

- URL is not reachable or returns a non-200 status — endpoint may return an error or empty fields
- Page blocks crawlers via robots.txt or bot detection — metadata may be partial or missing
- JavaScript-rendered pages where meta tags are injected client-side may not be captured
- Malformed or relative URLs passed as input will fail the required absolute URL validation
- Pages with no meta tags return mostly empty fields but do not error

## How this service works

Get structured metadata for any public web page in one call: title, meta description, canonical URL, Open Graph and Twitter card tags, favicons, JSON-LD schema types, language and the heading outline. Use it to build link previews and social cards, classify or dedupe URLs, and run SEO and AI-readability audits - far cheaper than fetching and parsing the whole page.

## Output

Returns a structured JSON object containing the page title, meta description, canonical URL, Open Graph tags (og:title, og:description, og:image, og:type, etc.), Twitter card tags, favicon URLs, JSON-LD schema types found on the page, detected language, and an array of headings (H1–H6).
