## 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 screenshots-by-underscoredone-2d1cc909 -d '<json body>'
```

Example prompt: Take a full-page screenshot of https://example.com at 1280x800, scroll through to load all lazy images first, and hide any cookie consent banners before capturing.

## When to prefer this

Use this endpoint when you need a pixel-accurate, JavaScript-rendered screenshot of a live webpage — especially when the page relies on dynamic content, lazy-loaded images, or has intrusive popups that should be suppressed before capture. Prefer it over HTML-only scrapers when visual fidelity matters.

## Known failure modes

- URL is unreachable or returns an error — capture fails with network error
- Page takes too long to reach the wait_until condition — timeout error
- Invalid URL format provided — validation error
- Viewport dimensions are invalid or unsupported — bad request error
- Website blocks headless browsers — may return blank or partial render

## How this service works

Renders a webpage exactly as a real browser would, including all its scripts and dynamic content, then takes a picture of it. You can capture just the visible area or the whole scrollable page, choose the screen size, wait for slow-loading images to finish, and hide cookie banners or popups before the picture is taken.

## Output

A rendered image of the target webpage, captured after browser-level JavaScript execution, optional lazy-load scrolling, and popup suppression — either the visible viewport or the full scrollable page, depending on settings.
