I.)
1 Credit=CREATE NEW Landing Page or 1 Credit=MAX ACTIV Landing Page?
For Example Tier 4 (4.000 Credits): I create 4.000 Landing Page each Month. I do this 3 Month. Do I have 12.000 active Landinpages after 3 Months?

II.)
What Fields can be customized? In your Marketing Video is mentioned only "First Name". In my Business we don´t use "First Name", but "Last Name".
Is there a List of customizable Fields?

III.)
Any kinds of API or Integration (planned)?
My Usecase would be "Create individual Video with other Tool and embed this Video on GenPage Landing Page".

IV.)
BYOK planned? Which Tier?
OpenAI would be best, but every kind of BYOK would be usefull.
