When to Use

Use this tool when you need to start the purchase flow for an available domain via stripe checkout.

important: before calling this tool, you must first call check_domain to get the price, then clearly show the user the price and get their explicit confirmation before proceeding. never call buy_domain without the user seeing and approving the price first.

the registrant contact details are required because the domain will be registered in the buyer's name (they become the legal owner). whois privacy is enabled by default, so these details are not publicly visible.

creates a stripe checkout session. returns a checkout url that the user should open in their browser to complete payment securely via stripe, plus the order id for tracking.
