3POST /capture with JSON body for complex options (dark mode, block ads, scroll, custom JS execution before capture).
4Returns image as binary or as a CDN URL (set `format=url`) for use in HTML/email.
5Average response time: 2-4 seconds for full-page renders.

Frequently asked questions

Real answers to questions developers ask before integrating.

Can I screenshot pages behind login?

Yes — pass `cookies` array or `headers` (e.g., Authorization) to authenticate before capture.

Does it execute JavaScript?

Yes — full Chromium with JS enabled. Use `wait_for` selector or `delay_ms` to wait for dynamic content.

Can I block ads or trackers?

Yes — set `block_ads=true` and `block_trackers=true`. Cleaner screenshots, faster renders.

What's the max viewport?

Up to 4K (3840×2160) on Ultra+, 1920×1080 on standard.

Can I screenshot at mobile sizes?

Yes — pass any width/height. We have preset device types: `device=iphone15|pixel8|ipadpro`.

Are screenshots cached?

Yes — identical requests return cached results for 1 hour. Pass `cache=false` to force fresh capture.
