One API call tells you whether AI crawlers are allowed to read your site and whether your pages are structured so AI search can cite them. robots.txt bot rules, llms.txt, JSON-LD, meta tags and sitemap — scored, with fixes.
Recommended next step. A free key raises you from 3 audits/day to 50 audits/month. Just an email address — no card, no password. The same key keeps working if you ever move to a paid plan.
