# RingHuman > RingHuman calls customer support for you: an AI voice agent dials the company, navigates the phone tree, waits on hold, and rings your phone the moment a real human answers. You pay 2x the actual call cost. It never asks for or speaks an OTP, password, PIN, SSN, seed phrase or private key, and it cannot move money or change account settings. For sensitive accounts (banks, crypto, tax, healthcare) it bridges you in before any account details are discussed. ## CLI Install: curl -fsSL https://ringhuman.com/install.sh | sh or `npm i -g @profullstack/ringhuman` (Node >= 18), or `bun add -g @profullstack/ringhuman`. ringhuman login --api-key ringhuman routes search "comcast" ringhuman call --route --reason "billing" --callback +1... ringhuman calls watch ringhuman balance The CLI talks to https://ringhuman.com (override with RINGHUMAN_API_URL). ## Links - [Home](https://ringhuman.com/) - [Browse support routes](https://ringhuman.com/search) - [Start a call](https://ringhuman.com/call/new) - [npm package](https://www.npmjs.com/package/@profullstack/ringhuman) - [Source](https://github.com/profullstack/ringhuman.com)
