## 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 coco-link-preview-tool-fa2b47ae
```

Example prompt: Can you grab a link preview for https://example.com/article — I want to know the page title and whether it's accessible?

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.001 USDC) single-URL link preview — specifically to extract the page title and confirm HTTP reachability — as part of a personal lab or AI experiment workflow on CoCo. Best for lightweight link validation and metadata extraction rather than deep content scraping or structured data extraction.

## Known failure modes

- Page not found — 404 status if the URL does not exist
- Timeout — slow or unresponsive target servers may cause delays or failures
- Blocked by target — some sites block headless/bot requests and may return 403
- Invalid URL — if the query parameter is malformed or missing, the request may fail
- Paywalled or JavaScript-rendered pages may return incomplete or empty titles
