## 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-metadata-extractor-409961c7 -d '<json body>'
```

Example prompt: Can you extract the metadata from https://techcrunch.com/2024/01/15/ai-startup-funding — I need the page title, meta description, Open Graph tags, and any schema.org structured data it has?

## When to prefer this

Choose this endpoint when you need fast, structured extraction of HTML metadata (titles, Open Graph, schema.org, canonical URLs) from a web page without needing to parse or process the full page body. It is ideal for link preview generation, SEO audits, content indexing, and metadata enrichment pipelines. Prefer this over a full web scraper when you only need head-level metadata and want a clean JSON response at low cost ($0.01 USDC per call via x402 micropayment).

## Known failure modes

- URL is unreachable or returns a non-200 status — result may be empty or partial
- Page uses heavy JavaScript rendering and metadata is not in static HTML — dynamic content may not be extracted
- URL is behind a paywall or authentication — returns empty or minimal metadata
- Malformed or missing input URL — returns validation error
- Rate limiting or bot protection on target site — request may fail or return blocked page metadata
- Network timeout on slow-loading pages — may return partial results with warnings
