Project Description

This project combines an x402 endpoint and a World mini app to allow anyone to call your phone at the price you choose. You can choose to restrict calls to humans, in which case only users of the World miniapp who verify their humanity will be able to call. In all other cases, anyone using the x402 endpoint can start a call, this includes AI Agents! You can make calls independent of location, to anyone, anywhere, on their phone number. Users are self-sovereign of their attention; they choose how much their attention is worth by setting how much people should pay to call them. People will call only if it's worth it: low noise, high signal.

How it's Made

Phone calls are hosted using Twilio, users never learn the phone number of the person they are calling. World identification, proof of humanhood, and USDC payments are live on World mainnet and leverage Worldchain's minikit. At this time, the x402 endpoint is on Sepolia and limited by the Coinbase SDK to 0.1 USDC / payment.
