Are there any of those CLI clients (coded in plain and simple C, or basic python/perl without 1 billion of expensive dependencies) able to access those 'coding AI' prompt anonymously then rate limited?

If no anonymous access is provided, is there a way to create an account with a noscript/basic (x)html/classic web browsers in order to get an API key secret?

Because I do not use web engines from the "whatng" cartel.

To add insult to injury, my email is self-hosted with IP literals to avoid funding the DNS people which are mostly now in strong partnership with the "whatng" cartel (email with IP literals are "stronger" than SPF since it does the same and more). An email is often required for account registration.
