Frequently Asked Questions

CaptureAPI is a developer-friendly REST API that lets you capture website screenshots, convert HTML to PDF, and generate dynamic Open Graph images. You send an HTTP request with a URL or HTML content, and we return the rendered output in seconds.

CaptureAPI is built for developers, SaaS teams, and agencies who need to automate visual capture at scale. Common users include monitoring tools, CMS platforms, reporting dashboards, and social media automation services.

Yes. The Free plan includes 50 screenshots per month at 720p resolution with no credit card required. It is ideal for testing, prototyping, and small personal projects.

No. CaptureAPI is a cloud-hosted REST API. You make HTTP requests from any language or platform — no SDKs, browser binaries, or server-side dependencies required.

We offer four plans: Free (50 screenshots/month), Pro ($19/month for 2,000 screenshots), Business ($49/month for 10,000 screenshots), and Enterprise ($99/month for unlimited screenshots). Pro and Business plans launch in Q2 2026.

When you reach your plan limit, additional API requests will return a 429 (Too Many Requests) response. You can upgrade your plan at any time from the dashboard. We never charge overage fees without your explicit consent.

Yes. All plans are month-to-month with no long-term contracts. You can upgrade, downgrade, or cancel from your dashboard at any time. Changes take effect at the start of your next billing cycle.

Most screenshots are delivered in 1-3 seconds depending on the target page complexity. Simple pages render in under 1 second. We use headless Chromium with optimized rendering pipelines on globally distributed infrastructure for the lowest latency possible.

Screenshots support PNG, JPEG, and WebP formats. PDF generation outputs standard PDF documents with full control over page size, margins, headers, and footers. OG images are returned as PNG by default.

Yes. Set the fullPage parameter to true, and CaptureAPI will render the entire scrollable page into a single image. This is available on Pro plans and above.

You can specify any viewport width and height via the width and height parameters. Common presets include 1280x720 (HD), 1920x1080 (Full HD), and 3840x2160 (4K). Custom sizes are supported on all plans.

Yes. You can use the waitForSelector parameter to wait for a specific CSS selector to appear in the DOM, or set a custom delay in milliseconds. This ensures SPAs, lazy-loaded images, and JavaScript-rendered content are fully loaded before capture.

Yes. All API communication uses HTTPS/TLS encryption. Screenshots and PDFs are generated in isolated, ephemeral containers and deleted immediately after delivery. We do not store, cache, or log any captured content.

Yes. Our rendering engine blocks requests to private IP ranges, localhost, and internal network addresses. We maintain a deny-list of reserved IP blocks and validate all target URLs before rendering.

Yes. CaptureAPI is hosted in the EU and follows GDPR principles. We process data only as instructed, retain no captured content after delivery, and our privacy policy details how we handle account data. See our Privacy Policy for details.

API keys are hashed before storage. They are never logged or displayed in full after creation. You can revoke and regenerate keys from your dashboard at any time. We recommend using environment variables to store your keys.
