Registering a Domain

Domain registration is a two-step process for safety:

1. First, check domain details and pricing:

2. If you're sure you want to purchase, confirm the purchase:

Example Prompt:

register bingbang1234.com

Example Response:

I'll start the domain registration process for bingbang1234.com. This is the first step, which will show you the registration details without actually purchasing the domain yet.

...

Domain bingbang1234.com is available for registration!
Pricing: $9.98 for 1 year
Registration details:
