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, page title, format ('png'), the CSS selector used, viewport dimensions, final redirected URL, image size in bytes, and the full base64-encoded PNG of the captured element.
Example use cases
Monitoring competitor hero banners
“Grab a screenshot of the '.hero-banner' element on https://competitor.com every day so I can track how their homepage changes — use a 1280px wide viewport and wait for networkidle.”
Capturing chart widgets for reports
“Take a screenshot of the '#revenue-chart' element on our internal dashboard at https://dashboard.mycompany.com and give me the image so I can drop it into a report — use a 1920px wide viewport.”
Visual regression testing a UI component
“Screenshot the '.checkout-button' element on https://staging.myshop.com with a 375px wide mobile viewport waiting for domcontentloaded, so I can compare it against the production version.”
Technical details
Endpoint
POSThttps://screenshot.payapi.market/capture/element?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to capture a specific DOM element rather than the full page or a PDF — ideal for extracting charts, UI components, product cards, or any isolated section identified by a CSS selector. Prefer this over full-page screenshot endpoints when only a portion of the page is relevant, reducing image size and noise.
Side effects
- Invalid or unreachable URL returns an error (internal/loopback hosts are rejected)
- CSS selector not found on page results in an error response
- Page fails to reach the requested load state (timeout)
- Viewport dimensions outside allowed range (320-3840px) are rejected
- Payment failure via x402 protocol blocks the request
