search_domains
Search domain availability and price
Use this when someone wants to know whether specific domain names can be registered and what they cost. Checks up to 20 names (exact domains, or a name plus endings) with the live registrar and returns, for each, whether it can be registered, the first-year and renewal price in USD, and the reason when it cannot. For many names at once, use screen_domains first.
