## 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 url-intel-api-url-metadata-extraction-d2d1a9f2 -d '<json body>'
```

Example prompt: Can you pull the title and meta description for https://example.com so I know what that page is actually about?

## When to prefer this

Use this endpoint when you need quick, structured URL metadata (title and meta description) without running a full browser or headless scrape. It is ideal for AI agents that need to enrich, categorize, or vet URLs at low cost ($0.01/call) without spinning up browser infrastructure. Prefer it over full web scrapers when only top-level page metadata is needed.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — may return empty or error fields
- URL points to a page with no meta tags — returns empty strings for title/meta_description
- Malformed or invalid URL input — likely returns a 400 or error response
- Target page uses heavy JavaScript rendering — metadata may not be fully extracted if the page requires JS execution
- Rate limits or payment issues — returns 402 if payment is not properly attached
