Screenshot API

See What a Page Shows Without Opening It Yourself.

Pass a URL. The API opens it in a real browser, captures it and returns a link to the image, with the address the browser ended up on after redirects. The defaults give a 1366 × 768 JPEG of the visible part of the page.

Where a Capture Becomes Evidence.

Triage

Phishing Review

Look at a suspected phishing page from a browser that is not on an analyst’s machine, and keep the capture with the ticket.

Use case

Record

Impersonation Evidence

Keep what a lookalike domain showed, with check_date and the redirected_url its redirects led to.

Use case

Escalate

Takedown Requests

Attach a dated image of the offending page to the request a registrar or host will review.

Use case

Redirects, Errors and Retries.

Redirectsredirected_url is where the browser landed, which is often not where the link pointed.
With page dataWeb Data with screenshot=true returns a capture together with the page’s HTML, links, headers and cookies.
Busy and errors503 means the service is busy: retry shortly. 400 when url is missing or an option is out of range. See errors.
Rate limitsPlan-dependent. The default is one request per second per key and endpoint. See rate limits.

Questions About Screenshot API

How do we capture a whole page, lazy-loaded images included?

Set full_page=true and lazy_load=true. The browser then scrolls through the page before it captures all of it, from top to bottom.

How do we capture a page that loads slowly?

Set mode=slow and a longer timeout, and add a delay when the page animates in after it loads.

Should we use Screenshot or Web Data?

Web Data with screenshot=true adds a JPEG of the rendered page to its response, with no capture options. Use Screenshot when the capture needs a set viewport, a full page, PNG, longer waits or a single element.

How is the Screenshot API priced?

As part of an API services plan, by volume and frequency. Each capture is a lookup and counts against your plan’s quota at one unit per request. See Data & API pricing.

Can analysts capture pages without writing code?

Yes. Instant Lookups in Deep Search & Insights includes Screenshot, next to the Technology and Web Data lookups.
