## 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 agent-data-api-web-metadata-extraction-344e5bc7
```

Example prompt: Can you pull the metadata — title, description, and Open Graph tags — from this page: https://example.com/article/some-news-story?

## When to prefer this

Use this endpoint when you need structured metadata (title, description, Open Graph tags) from a web page without needing the full page text or Markdown content. It is faster and cheaper than full text extraction endpoints when you only need head-level metadata. Ideal for link previews, SEO audits, content enrichment pipelines, and validating social sharing metadata. Prefer this over full web extraction when you don't need the body text of the page.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — endpoint returns an error response
- Page uses JavaScript rendering only and metadata is not present in raw HTML — may return incomplete or empty metadata
- Invalid or malformed URL provided — returns a validation error
- Payment not completed or x402 USDC payment fails — request is rejected
- Rate limiting or bot-blocking by target site — may result in incomplete response

## How this service works

Pay-per-call data services for AI agents: web extraction (text, Markdown, metadata), PDF-to-text, RSS/Atom parsing, FX and crypto prices, weather, DNS and email validation. All paid endpoints use the x402 payment protocol (USDC).

## Output
