Here are a couple of suggestions:
"How much would it cost to launch one Thingy on my website?"
"What’s included in the Thingy platform license?"
"Can I get pricing for adding video or voice interactions?"
"How does billing change if I have 5,000 users per month?"
"Is there a one-time setup fee, or is everything subscription-based?"
"What’s the cost difference between a banner bubble and full-screen experience?"
