What if they don't reply?
You pay nothing. Instant Expert sends follow-up reminders, and if the person hasn't booked or answered within 7 days, the request expires and any hold on your card is released.

Can an AI agent ask one of these Freeport-McMoRan operations leaders a question?
Yes. An agent with a USDC wallet on Base can ask one question without an Instant Expert account.
