## 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 red-web-utils-metadata-extractor-2de90846 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need lightweight, structured metadata extraction from a single URL without full page scraping — ideal for link enrichment, social preview generation, SEO auditing, or structured-data inspection. It is pay-per-call with micro-pricing ($0.001 USDC), making it cost-effective for on-demand agent workflows. Prefer this over full crawlers when you only need head-level metadata, not page body content.

## Known failure modes

- URL is unreachable or returns a non-200 status — status field will reflect the HTTP error code
- Page has no Open Graph or JSON-LD metadata — those fields return empty objects or arrays
- JavaScript-rendered content not captured — only static HTML metadata is extracted
- Malformed or non-URL input causes a request failure
- Rate limiting or bot-blocking by the target site may result in empty or partial metadata
