## 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 agent-web-access-screenshot-92d27cd8
```

Example prompt: Can you take a full-page screenshot of https://example.com at 1280px wide and show me what it looks like?

## When to prefer this

Choose this endpoint when you need a visual, pixel-accurate representation of a live webpage — especially when the page relies on JavaScript rendering and you need to see the actual rendered UI rather than raw HTML. Ideal for visual QA, monitoring, archiving page appearance, or feeding screenshots into vision-capable AI models. Prefer this over HTML/markdown scraping endpoints when visual layout matters.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns error or blank screenshot
- Invalid or malformed URL — request fails with validation error
- Page takes too long to render (timeout) — may return partial or error response
- Network unreachable or DNS resolution failure — returns error
- fullpage parameter not recognized if not passed as string 'true'/'false'

## How this service works

Pixel-accurate PNG screenshot of any live web page, rendered in a real browser at a chosen viewport width, viewport-only or full-page. Returns base64 PNG. Use it when an agent needs to SEE a page: visual verification of a deploy, layout and design capture, confirming a rendered chart or map, or feeding an image to a vision model that cannot read HTML.

## Output

Returns a JSON object containing the original URL and a base64-encoded PNG image of the rendered page. The image reflects the live, JavaScript-rendered state of the page at the specified viewport width, either cropped to the viewport or capturing the full scrollable page depending on the fullpage flag.
