Bandwidth Build – Voice API

Bandwidth Build is a self-serve trial for Bandwidth’s Voice API. Sign up, get a provisioned US number, and make your first call in minutes. No credit card, no sales call, no waiting.

Free trials include 3,000 credits and a 10DLC US phone number for the first 30 days. Supported use cases include inbound and outbound calling, voice AI applications, IVR and call flows, and call recording and transcription. It all runs on the same network as Bandwidth’s Universal Platform.

When your trial credits run out, you can buy more directly in the app. Packages start at 25,000 credits for $49, with discounts on larger volumes. Auto-recharge keeps things running if you’d rather not think about it.

This is for US phone nubmers only. Get started at bandwidth.com/build-sign-up or through the Bandwidth CLI.
