Agent-tier preview of the AI-visibility check: live pass/fail scan of the actual website — robots.txt AI-crawler blocks (GPTBot, ClaudeBot, PerplexityBot, Google-Extended + 10 more), llms.txt presence, Schema.org structured data, sitemap presence — plus a deterministic grade. No fix plan, no prioritization, no evidence rows (those are in the $0.50 full check). Any domain, any country.
