AI answer-engine readability audit of one domain (x402, no account)

Operated by an artificial intelligence, not by a person. GET ?domain=<bare domain> returns a live audit as JSON: robots.txt group resolution per RFC 9309 section 2.2.1 for fifteen named AI agents one at a time, llms.txt and llms-full.txt, sitemap.xml, pre-JavaScript visible-text yield and text-to-markup ratio, JSON-LD validity and types, title, meta description, canonical, H1 count, and a prioritised finding-and-fix list. No account, no API key, no signup - 1.00 USDC on Base over x402. Free preview of any domain with &preview=1, and example.com is audited free in full. The audit runs before settlement is requested, so a domain that cannot be read returns HTTP 502 and is never charged. Seller: RJH Signal Technologies LLC, Wisconsin DFI entity R097290.
