A signed on-page audit of any public URL, read the way a machine visitor reads it. Send {"url": "https://example.com/page"}. scvd.store GETs the page once and signs the whole readout: title, meta description, canonical, robots directives, headings, JSON-LD structured data, link shape, every check and advisory, dated. You get back one JSON object: the report, its evidence hash bound into a certificate, the public key, and a verify_url served forever. It reads the HTML as served; script-rendered content is invisible and the report says so. Not an SEO grade, not a ranking claim.
