Short answer: PagePeeker’s public documentation describes website screenshots and thumbnails, but does not explain how to capture a page that requires a login. Before relying on it, confirm with PagePeeker that it supports your app’s authentication method. If it does not, use a browser capture service that documents the relevant credentials or log in with browser automation and take the screenshot from that authenticated session.

What PagePeeker documents about protected pages

PagePeeker describes itself as a website screenshot and thumbnail service. Its public pages mention an account-based API, cached renders, and full-page screenshots for premium customers. They do not explain how to provide cookies, HTTP Basic credentials, target-site authorization headers, or a browser session for a password-protected page. Its API navigation redirected to the homepage when reviewed, so the available public information does not establish whether authenticated capture is supported. PagePeeker’s homepage and FAQ

That distinction matters: sending a URL to a screenshot service is not the same as sending it a logged-in browser session. Without suitable authentication, the resulting image may show a sign-in page or an access-denied message instead of the app.

Choose a capture method that matches the login

First identify how the app authenticates you. The right approach depends on whether access is granted through an HTTP challenge, a session cookie, a request header, or an interactive browser login.

App authentication What the capture needs Practical approach
HTTP Basic Authentication The username and password for the browser’s HTTP authentication challenge. Use a capture service that explicitly documents HTTP credential support. Cloudflare Browser Run’s screenshot endpoint accepts an authenticate object for this kind of challenge. It does not automatically handle an app’s custom login form. Cloudflare Browser Run screenshot documentation
Session cookie Valid cookies for the target domain and the relevant path. Use a service that supports cookie injection, or reuse a logged-in browser context. Cookies can expire or be scoped so they do not apply to the page you are capturing. Treat them like passwords. Cloudflare Browser Run screenshot documentation
Authorization token or custom header The target app’s required request header, such as a bearer token. Use a browser capture method that can set target-site headers. Cloudflare documents setting extra HTTP headers. The target app’s token is separate from the screenshot provider’s own API key. Cloudflare Browser Run screenshot documentation
Interactive or browser-state login A completed login flow and its browser state, including any redirects or client-side state the app requires. Automate login and capture in the same authenticated browser context. Playwright documents saving and reusing authentication state for tests. That state may contain credentials that allow account impersonation, so protect it as a secret and keep it out of source control. Playwright authentication documentation

A safe workflow for a PagePeeker capture

  1. Confirm permission. Make sure you are authorized to access and capture the app. Start with a non-sensitive staging page when possible.
  2. Identify the login mechanism. Determine whether the app uses Basic Auth, cookies, a request header, or an interactive login and browser state.
  3. Verify PagePeeker support. Check its current API documentation or ask its support whether it accepts the specific credential or authenticated state your app requires. The public material described above does not settle that question.
  4. Use a documented alternative if needed. If PagePeeker cannot handle that authentication method, use a browser capture service that explicitly supports it or run browser automation in an environment you control.
  5. Wait for actual page readiness. For a JavaScript-heavy app, wait for an app-specific element that indicates the intended content has loaded. Cloudflare’s documentation describes waiting for a selector when it signals readiness. Cloudflare Browser Run screenshot documentation
  6. Inspect the resulting image. Confirm it shows the expected authenticated content rather than a sign-in form, authorization error, stale view, or partially rendered dashboard.

Protect credentials and browser state

Passwords, session cookies, bearer tokens, and saved browser state can grant access to an account. Keep them in protected server-side secrets or files, use the least-privileged account that can perform the capture, and avoid putting credentials in public pages, shared screenshot URLs, source repositories, or logs. Revoke temporary credentials when they are no longer needed. Playwright specifically warns that saved authentication state can contain sensitive cookies and headers. Playwright authentication documentation

Or skip the browser setup

ScreenshotNeo is a screenshot API and MCP server for developers. Its API accepts cookies, custom headers, and an Authorization value, which can help with pages whose access depends on those request details; it does not replace an interactive login flow that must be completed in a browser. Cookie and consent banners, newsletter popups, and chat widgets are removed before capture, and each step can be turned off. Bot checks, blank pages, timeouts, failed loads, and cache hits are not billed; response headers report the page verdict and billing status. AI agents can use its MCP server tools, including take_screenshot, get_page_info, and capture_pdf. Learn about ScreenshotNeo.

For an app where you are authorized to set the required cookies or headers, a basic one-call request looks like this:

PagePeeker’s FAQ says cached renders remain available for several days and that API usage includes more than generating a new render: displaying a cached thumbnail, checking availability, and other API calls also count. The listed plan limits therefore should not be read as a number of newly rendered, authenticated pages. PagePeeker FAQ

Troubleshooting an incorrect screenshot

  • The image shows a login page. The capture likely did not receive the required authentication, the session expired, or the cookies were not valid for that domain or path. Confirm the mechanism and ask PagePeeker whether it supports it.
  • The image shows an authorization error. Check that the target app received the right credential or header and that it has access to the requested page. Do not confuse the screenshot service’s API key with the app’s credential.
  • The dashboard is blank or incomplete. The app may still be rendering client-side content. Wait for a selector that appears only when the desired content is ready, then inspect the capture again. Cloudflare Browser Run screenshot documentation
  • A cookie-based capture works once, then fails. Sessions can expire; domain and path scope can also prevent a cookie from applying to the capture URL. Refresh the session securely and avoid reusing stale state.
  • The result is an old page. PagePeeker says it caches renders for several days. Check whether the returned thumbnail is cached and whether the current plan or API operation allows a fresh render. PagePeeker FAQ
