How this service works
146 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
Returns a JSON object containing the original URL, the viewport width used, whether full-page capture was performed, the MIME type (image/png), and the screenshot as a base64-encoded PNG string ready to embed or decode.
Example use cases
Visual QA for deployed web app
“Take a screenshot of https://myapp.example.com after the latest deploy and show me what the homepage looks like — use 1280px wide and capture the full page.”
Competitor landing page snapshot
“Grab me a screenshot of https://linear.app at desktop width so I can see how their homepage is currently laid out.”
Thumbnail for link preview
“Capture a screenshot of https://news.ycombinator.com at 1280 pixels wide (just the visible viewport, not full page) so I can use it as a preview thumbnail.”
Technical details
Endpoint
GEThttps://fastx402.tools/screenshot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call, no-account screenshot of any public URL as a base64 PNG — especially useful for AI agents that need visual verification, link previews, or visual QA without setting up a headless browser. Prefer it over full browser automation services when you just need a single-shot image at low cost ($0.005 per call).
Side effects
- Invalid or unreachable URL returns an error (non-2xx response or DNS failure)
- Width outside 320–1920 range may be rejected or clamped
- Private/intranet URLs will not be accessible from the cloud renderer
- Very large full-page captures may time out or exceed payload size limits
- Paywalled or login-gated pages will be captured in their unauthenticated state
