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.

Example use cases

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.”

Technical details

Endpoint

POSThttps://screenshots.underscoredone.com/capture

When to prefer

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.

Side effects

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

Input

Schema · Request body

Field	Type	Description
url	string	The web address of the page to capture.
viewport	object	The width and height of the browser window used to render the page, in pixels.
full_page	boolean	If true, captures the entire scrollable page instead of just the visible area.
load_lazy	boolean	If true, scrolls through the page first so lazy-loaded images and content finish loading before the capture.
wait_until	string	When to consider the page ready to capture: load, domcontentloaded, networkidle0, or networkidle2.
allow_popups	boolean	If false (default), cookie banners, consent popups, and chat widgets are hidden before capturing.

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
