check_ai_crawler_readinessCheck 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.

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
