## How to call it through Zero

```sh
zero fetch --capability aiservices-url-metadata-lookup-66838966
```

Example prompt: Can you fetch the metadata for https://example.com — I need the page title, description, and any Open Graph tags it exposes?

## When to prefer this

Use this endpoint when you need to quickly enrich a URL with human-readable metadata (title, description, OG tags) without scraping the full page yourself, and you are operating in an agentic context that supports x402 micropayments on Base with USDC. It is ideal for link preview generation, content cataloging, or enriching a list of URLs with descriptive metadata.

## Known failure modes

- URL is unreachable or returns a non-200 status — may return an error or empty metadata
- Invalid or malformed URL input — returns a validation error
- Payment failure via x402 protocol — request is rejected before processing
- Target page blocks crawlers — may return incomplete or no metadata
- Timeout if the target URL is slow to respond
