This lets Claude make actual phone calls through the StablePhone API using x402 payments. You can have an AI call someone to schedule a meeting, leave voicemails, qualify leads, or check business hours, then get back a transcript and summary. Calls cost 54 cents each, run up to 30 minutes, and support call transfers to humans if needed. You can also buy dedicated phone numbers for $20 to use as caller ID, plus there's an iMessage/FaceTime lookup feature. The voice options are decent (defaulting to an American female named Nat) and the API is straightforward POST and polling. Good for automating outreach or gathering info without writing your own telephony code.
