> PageWire Web Page Metadata Extraction is a paid API for AI agents from pagewire.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).

## 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 pagewire-web-page-metadata-extraction-a78ce8c6
```

Example prompt: Can you grab the metadata from https://openai.com/blog — I need the page title, description, Open Graph tags, and any JSON-LD structured data on it?

## When to prefer this

Choose this endpoint when you need structured metadata (title, description, OG tags, JSON-LD, canonical URL) from a public webpage without managing API keys or subscriptions. It is ideal for one-off or low-volume agent workflows that need pay-per-call pricing in USDC. Prefer this over full-page Markdown conversion when you only need metadata rather than the full page content.

## Known failure modes

- Non-public or paywalled URLs may return incomplete or empty metadata
- Pages requiring JavaScript rendering may return minimal metadata
- Invalid or malformed URLs return a 4xx error
- Slow-loading pages may time out
- Pages with no meta tags return null/empty fields for description, og, twitter, jsonld

## How this service works

Pay-per-call web reading API and MCP server for AI agents: page to Markdown, metadata and small crawls. USDC via x402 or MPP, no account, no API key.

## Output

A JSON object containing the page URL, HTTP status code, title, meta description, detected language, canonical URL, Open Graph properties object, Twitter card properties object, an array of JSON-LD objects, and an array of favicon/icon references.
