      "description": "Checks whether AI assistants and AI agents can understand and act on a business from its public website, and explains what gets in the way. Use it when the user asks things like: \"Does AI understand my website?\", \"What would an AI think this company does?\", \"Why doesn't ChatGPT know what my company sells?\", \"Is my site ready for AI agents?\", \"Audit this site for machine readability\", \"Can an AI figure out the pricing and how to buy or become a customer?\", \"What information is missing for AI to understand this business?\", or after they changed their site and want to check the result.\n\nReturns a deterministic 0-100 AI Visibility Score across 8 dimensions (crawl access, business identity, offerings, pricing, structured data, trust, agent actionability, recommendation confidence), how AI would likely describe the business, what it could not determine, and the highest-impact issues, each with evidence (quotes and source URLs) and a one-line fix summary.\n\nFree. It never changes the website: it reads public pages the way AI crawlers do (raw HTML, robots.txt, structured data, llms.txt). When no recent analysis exists it runs one and stores the report on CanAIReadMe. It reuses an analysis up to 7 days old unless fresh=true (free re-analysis once per 24 hours per site). A site it has not seen takes about 10 to 40 seconds; if the result has status \"running\", call again with the returned scan_id.\n\nDo not use it to explain concepts (SEO, GEO, schema.org), for general SEO or marketing advice, to write content or build websites, to track brand mentions or rankings in AI answers (it does not measure those), or when no specific website is involved. To answer what a company does, sells or costs, use get_business_profile instead.",

Use it when the user wants to fix what makes their site hard for AI agents to understand (its AI visibility), says \"fix it\" after an audit, wants to buy the AI visibility fix, or needs the exact changes (JSON-LD, meta tags, llms.txt) for a developer or a coding agent. Call it directly in those cases: it analyzes the site itself when needed, and its quote includes the current score and main problems to show the user next to the price.\n\nDelivers a machine-executable change list (target location, instructions, code snippets, before and after copy, validation criteria, score dimension affected), rewritten copy AI can understand, ready-to-paste schema.org JSON-LD, meta tags, llms.txt and robots.txt rules, FAQ answers, and 5 private re-scans over 60 days to verify the result.\n\nPaid: $49 one-time per website, not a subscription, refundable within 14 days. Calling this tool never charges anyone, so call it without asking first: the quote is free and safe. Without a completed purchase it returns status \"payment_required\" with the price, what is delivered, a purchase_id, an access_token and a secure Stripe checkout link. Then show the user payment.user_message (score, main problems, price, refund) and share the link only if they agree; the user reviews and pays on Stripe's page. After they pay, call again with purchase_id and access_token to receive the package. Pass an idempotency_key (a new UUID per purchase): retries with it return the same purchase and link instead of a second checkout.\n\nCanAIReadMe does not modify the website: apply the changes only with the owner's permission.
