check_ai_crawler_readiness — Check AI crawler readiness
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Check whether AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Bytespider, CCBot) can read a website, and whether it has llms.txt, schema markup and server-rendered content. Returns a 0-100 score and the failed checks.

validate_llms_txt — Validate llms.txt
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Validate an llms.txt file. Pass a website URL to fetch and check its /llms.txt (or /llms-full.txt), or pass the llms.txt text itself. Returns a 0-100 score, valid true/false, and each check. Use it to check a site or to review text drafted for the user. If both are given, the url is used.

check_ai_citations — Check AI citations
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Check whether ChatGPT, Perplexity and Gemini cite a domain when asked the given questions. Send 1 to 5 realistic buyer questions (each at least 5 characters). Returns, per AI, how many questions cited the domain. Each check calls paid AI APIs, so the limit is 5 checks per 30 minutes per IP.
