## 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 switch402-viewport-screenshot-5523af6d
```

Example prompt: Can you take a screenshot of https://example.com and show me what it looks like right now — just the visible part of the page, rendered with JavaScript?

## When to prefer this

Choose this endpoint when you need just the above-the-fold visible viewport (1280x800) of a page, not the full scrollable content. It is ideal for generating thumbnail previews, quick visual checks, or capturing the initial user-facing state of a page. Use the full-page screenshot sibling endpoint if you need the entire scrollable page. Prefer this over scrape endpoints when visual fidelity (layout, images, styling) matters rather than extractable text or structured data.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns error
- Page fails to render JavaScript correctly within timeout
- URL is malformed or exceeds 2048 character limit — validation error
- Private/localhost URLs rejected — must be a public http(s) address
- Network timeout if the target page is slow to load
