How this service works
Headless Chromium screenshots, PDFs, full-page captures and element captures, with x402 payments.
Output
Returns a JSON object containing the original URL, the page title, the image format (PNG), the viewport dimensions used, the final redirected URL, the image size in bytes, and the full screenshot as a base64-encoded PNG string ready for display or storage.
Example use cases
Visual regression monitoring for landing pages
“Grab a screenshot of https://mycompany.com at 1280x800, waiting for networkidle, so I can compare it to what it looked like last week and check for unexpected layout changes.”
Social media link preview thumbnail
“Capture a screenshot of https://techcrunch.com/latest at a 1200x630 viewport, waiting until the page finishes loading, so I can use it as a preview thumbnail for a shared link.”
Client proof of ad placement
“Take a screenshot of https://publisher-site.com/sponsored-article at 1280x800 so I can show my client proof that their ad is live and rendering correctly on the page.”
Technical details
Endpoint
POSThttps://screenshot.payapi.market/capture/screenshot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real browser-rendered screenshot of a public web URL returned as a base64 PNG — especially when accurate visual fidelity, JavaScript rendering, and configurable viewport sizes matter. It is ideal for visual monitoring, proof-of-render tasks, and thumbnail generation. Prefer it over HTML scrapers when you need the visual appearance rather than raw text content, and over static image fetchers when the page relies on JavaScript to render correctly.
Side effects
- Internal/loopback hosts (e.g. localhost, 192.168.x.x) are rejected with an error
- Invalid or unreachable URLs return a capture failure response
- Viewport dimensions outside allowed ranges (width 320-3840, height 240-3840) are rejected
- Payment failure or insufficient USDC balance prevents the call from completing
- Pages with aggressive bot detection may render incompletely or show CAPTCHA screens
- Very slow pages may time out before the requested load state is reached
