## 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 sift-web-tools-page-metadata-extractor-09e70ada
```

Example prompt: Can you pull the metadata from https://www.nytimes.com/2024/01/15/technology/openai.html — I want the page title, Open Graph tags, and any JSON-LD structured data on the page?

## When to prefer this

Use this endpoint when you need lightweight, structured metadata from a URL without fetching the full page content — ideal for SEO audits, link preview generation, schema.org validation, or enriching records with page titles and Open Graph data. Prefer /v1/fetch if you need the full readable text of a page, or /v1/screenshot if you need a visual render. This endpoint is the cheapest and fastest way to get structured metadata specifically.

## Known failure modes

- URL is unreachable or returns a non-200 status — call fails and no charge is made
- Page has no structured metadata — returns empty json_ld array and empty open_graph object
- URL parameter missing — returns 400 validation error
- Page blocks crawlers via robots.txt or rate limiting — may return error or incomplete data
- Malformed URL input — returns validation error

## How this service works

Page metadata: title, description, Open Graph, Twitter card, JSON-LD. All metadata of a web page: title, description, language, canonical URL, favicon, Open Graph, Twitter card and JSON-LD structured data.

## Output

Returns a JSON object containing the resolved page URL, the page title, an array of JSON-LD objects found on the page, and an Open Graph metadata object with any og:* tags present. Costs $0.002 USDC per successful call via x402 on Base.
