How this service works

Machine-facing browser QA API. Submit a public HTTPS URL and receive screenshots, accessibility findings, layout analysis, and a structured report across three browser viewports. x402 payment is required per report on the live service; see /.well-known/x402 for current payment options. Self-hosted instances can run in test mode without payment.

Output

Returns a check ID, a status field (e.g. 'queued'), a poll URL to retrieve the completed report, and a paymentMode indicator. Once the job completes (polled via the returned URL), the full report includes screenshots and accessibility findings across three browser viewports.

Example use cases

Pre-launch landing page audit

“Before I push this to production, can you run a full browser QA check on https://staging.myproduct.com and show me how it looks across all three viewports plus any accessibility issues?”

Client website accessibility report

“I need to send my client a QA report for their site — can you run a ViewportWitness check on https://www.clientwebsite.com and pull the accessibility findings and screenshots?”

E-commerce mobile rendering check

“Can you check https://www.mystore.com on ViewportWitness to make sure the homepage renders properly on mobile, tablet, and desktop, and flag any accessibility problems?”

When to prefer

Choose ViewportWitness when you need a combined visual and accessibility QA report across multiple viewport sizes (mobile, tablet, desktop) for a single public URL. It is ideal for pre-launch audits, client deliverables, or automated CI/CD checks where cross-viewport screenshot capture and accessibility analysis are needed together without managing your own browser infrastructure.

Side effects

Non-public or non-HTTPS URL returns a validation error
URL is unreachable or behind authentication — check may fail or return empty results
Job queued but never completes if the target URL is too slow or times out
Payment not settled — request rejected with 402
Invalid URI format in input causes immediate 400 error
