You can invite several of the 10 people on this list at once and cap your total spend, so you pay only for the ones who accept.

Yes. An agent with a USDC wallet on Base can ask one question without an Instant Expert account.

The person answers in writing or by voice note, and if nobody answers within 7 days, the payment goes back to the wallet automatically.
