AI crawler visibility audit: is your website visible to AI crawlers (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot) so ChatGPT, Claude and Perplexity can read and cite it? Fetched like an AI crawler, without JavaScript: robots.txt, llms.txt, sitemap, soft 404, JSON-LD, and which crawlers are blocked at the edge. $0.01 per check, one payment per check: every rule, a model verdict, a fix with evidence for every finding. Pass: a dated badge and a registry listing. No account, no human.
