The list covers 1 company: Evergy, based on profile data retrieved on October 23, 2026. Being listed here doesn't mean someone has agreed to take calls.
How much does it cost to reach Evergy finance leaders?
You choose the offer, starting at $5 per person. The offer is what the person receives, and Instant Expert's fee is added on top, so a $100 offer costs you $125. The fee is 20% of what you pay. You're charged only when the person books the call or sends the answer.
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. 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. Claude and ChatGPT can do the same through the Instant Expert connector: setup is at /docs/mcp for Claude and /docs/chatgpt for ChatGPT. x402 docs
