## 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 web-scraper-api-metadata-extraction-9e6a5eb7 -d '<json body>'
```

Example prompt: Can you pull the metadata from https://techcrunch.com/2024/03/15/openai-raises-new-funding/ — I need the title, description, Open Graph tags, author, and published date?

## When to prefer this

Choose this endpoint when you need structured page metadata (title, description, Open Graph, Twitter cards, dates, author, language) from a single URL quickly and cheaply at $0.002 per call, especially in agentic pipelines that require link previews, SEO audits, or article enrichment. Prefer this over full HTML scraping endpoints when you only need header-level metadata rather than full page text or link extraction.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — metadata fields will be null or the request may error
- Page blocks scraping bots via robots.txt or JS challenges — may return empty or partial metadata
- Malformed or missing meta tags on the target page — relevant fields will be null
- Payment failure via x402 protocol — request will not be processed
- Invalid or non-HTTP(S) URL provided — request will be rejected

## How this service works

HTML scraping (text, links, metadata, structured) with x402 payments and MCP server.

## Output
