Real checks, not a narrative: title/meta tags, mobile viewport, H1 structure, structured data, Open Graph, image alt-text, robots.txt, XML sitemap, server response time. Every check is the same passive request any crawler makes. Free, no signup, no wallet, cryptographically signed receipt.

Same endpoint agents can call via MCP or x402. Every scan returns a signed receipt — the verdict isn't just displayed, it's provable.
Technical/on-page signals only. No backlink profile, Domain Rating/Authority, keyword rankings, or competitor comparison — those require a paid index (Ahrefs/Semrush/Moz) not run here. A clean scan clears the technical floor rankings depend on; it does not guarantee rankings.
