How it works

Dexter picks up immediately. The conversation happens in real time, not a back-and-forth with a chatbot.

1

Call the number

Dial +1 (561) 940-2402. Dexter picks up in about a second.

2

Ask for what you want

"What sentiment APIs are available for SOL?" Dexter searches the marketplace and tells you what it found.

3

Dexter handles payment

It picks the best result, pays for it, and reads you back the response. You never touch a wallet.

4

Details get texted to you

Links, addresses, or anything long gets sent to your phone as a text so you can reference it later.

Everyone can call. If you link your phone number, Dexter remembers you.

What Dexter can do on a call

Everything it does on chat or MCP, but over the phone.

Search

Ask Dexter to find a service. Be specific or be vague. It searches the marketplace and reads you the top results.

Pay and call

Pick a result and Dexter pays for it and runs it. The cost comes out of a session balance, not your personal wallet.

Text messages

Dexter texts you anything that's easier to read than hear: links, addresses, detailed results.

Identity

If your phone is linked, Dexter recognizes you automatically. Otherwise, small transactions just work. Larger ones need a quick SMS code.

Security

No account needed to start

Anyone can call, search, and make small purchases. Your personal wallet is never involved.

Linked callers are recognized instantly

If you've linked your phone at dexter.cash, Dexter knows it's you from caller ID alone.

Nothing sensitive is read aloud

Keys, balances, and addresses are texted to you, never spoken on the call.
