## 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 agenttools-url-metadata-extractor-d1826c20
```

Example prompt: Can you fetch the metadata for https://openai.com — I need the page title, meta description, OG image, and favicon so I can build a link preview card.

## When to prefer this

Use this endpoint when an agent needs quick, structured metadata (title, description, OG tags, favicon) from any public URL without spinning up a full browser or HTML parser. It is ideal for building link preview cards, classifying external pages, or auditing SEO metadata. It is not suited for full HTML extraction, JavaScript-rendered SPAs, or accessing private network resources.

## Known failure modes

- Private or internal IP addresses blocked by SSRF guard — returns error
- Request times out if target server takes longer than 10 seconds to respond
- Response body exceeds 1MB cap — truncated or error returned
- Invalid or malformed URL returns validation error
- Target page returns 4xx/5xx — propagated as error
- Pages with heavy JavaScript rendering may return incomplete metadata (server-side fetch only)

## How this service works

Fetch a URL server-side and extract its title, meta description, Open Graph and Twitter card tags, canonical URL and favicon — the data agents need to preview or classify a link. SSRF-guarded: private networks are blocked, 10s timeout, 1MB cap. Use this when an agent needs to title, description, OG image and favicon of any page.

## Output

Returns structured metadata scraped from the target URL including: page title, meta description, Open Graph properties (og:title, og:description, og:image, og:url), Twitter card tags, the canonical URL, and the favicon URL. SSRF-guarded so private/internal network addresses are blocked.
