ViewportWitness by Apex Labs

Two low-resource paid agent tools complement browser QA: extractpage converts one public HTML page to deterministic Markdown for $0.005 USDC, and webrelease_gate passively checks one public page's release security controls for $0.05 USDC. Both share the Base/Solana x402 rails, idempotency protection, single-worker queue, and seven-day report lifecycle. They do not accept caller-supplied HTML, credentials, cookies, custom headers, uploads, or private-network targets.

Remote MCP server and x402 API for AI-agent browser QA. Submit a public HTTPS URL and receive screenshots, accessibility findings, layout analysis, and structured JSON across phone and desktop viewports.

The live service is at https://qa.honeygate.app. A standard report costs $0.08 USDC, read-only assertions cost $0.10, and a baseline comparison costs $0.12. Local instances can run in test mode without payment.
