Is there a free tier?

Yes, the page lists a free allowance of one hundred credits with no credit card required so developers can try the API before paying.

What output formats are supported?

Screenshots come in PNG, JPEG, WebP, and PDF and content extraction returns metadata, links, and clean Markdown or HTML.

Can the API handle bot detection?

CaptureKit advertises a stealth mode with residential proxies that bypasses common bot detection so captures complete on pages that block standard scrapers.

How fast are repeat requests?

Edge caching with TTLs up to thirty days serves repeat requests from a CDN and the site quotes an average response of about one and a quarter seconds.

What languages can I call the API from?

CaptureKit is language agnostic and the page lists JavaScript, Python, Go, Ruby, Java, and PHP examples for backend integration.

CaptureKit: Powerful API for automating web content extraction and screenshot capture

What is CaptureKit?

CaptureKit is a screenshot and web extraction API for developers who do not want to run their own headless browser fleet. A single request returns a pixel perfect screenshot in PNG, JPEG, WebP, or PDF and can also extract metadata, links, clean Markdown or HTML, and an AI generated summary. It is designed for backend workflows in SaaS, analytics, and AI tooling.

Why CaptureKit works

Teams that need screenshots or scraped page content usually end up maintaining Puppeteer or Playwright on their own infrastructure with all the device emulation, proxy, and bot detection issues that follow. CaptureKit handles those concerns as a managed API with edge caching so repeat captures are instant. That lets a small team ship features like link previews, compliance archives, or AI page summaries without owning the browser ops.

CaptureKit features

Multi format screenshots. Capture full page or viewport screenshots in PNG, JPEG, WebP, or PDF from one endpoint so the same workflow serves previews, archives, and exports.
Content and metadata extraction. Pull clean Markdown or HTML, metadata, and link graphs from any page so downstream tools work with structured input rather than raw rendering.
AI page summaries. Generate structured summaries of the captured page so AI agents and LLM pipelines can ingest web content without a separate parsing layer.
Device emulation library. Render against seventeen or more real device profiles so screenshots reflect what a mobile or tablet user actually sees.
Stealth mode with residential proxies. Bypass common bot detection through residential proxies so captures complete on pages that block standard datacentre traffic.
Edge cached delivery. Repeated requests for the same URL hit a CDN with TTLs up to thirty days so high traffic features stay fast and cheap.

SaaS engineers shipping link preview cards or compliance archives that cannot tolerate flaky in house browser automation.
AI platform teams feeding cleaned web content and screenshots into LLM agents and retrieval pipelines.
