Server instructions

Look up availability and pricing for specific domain names. `search_domains` returns whether each requested domain is available, its registration and renewal price for the ending's full registration term, and, for available domains we can register, a URL the user can open in a browser to complete registration on justdomain.ai. Most endings register one year at a time; .ai registers in two-year terms set by its registry, so a .ai figure is a two-year total and not an annual rate. Premium names are reported but cannot be registered through Just Domain yet, so they carry no URL. The tool is read-only: no order is created and no payment is taken inside the chat. Safe to call without authentication. Just Domain registers and runs domains; it does not yet support renewals, auto-renew, transfers in or out, or authorization (EPP) codes. Read the `domain://faq` resource before answering a question about anything beyond search.
