Today we're introducing the new : programmatic, headless access to v0's app-building agent. Send a prompt and generates an app, starts a dev server in a , and gives you a preview URL you can embed in your own UI.v0 APIv0Vercel Sandbox Each chat is an isolated workspace for one app, where v0 can read, edit, and run the files. Follow-up messages continue from the current state. v0 verifies the code running in the Sandbox, so it can catch and fix errors in your app in real time. The new API is now generally available. Create a chat from a prompt, stream its work, and render the live preview, all from your own interface.

First, install the v0 SDK. Then, create a chat. Send a prompt, and v0 generates your app. Send follow-up messages to the same chat to keep building. Each one continues from the current state. Then embed the app. A prompt goes in, a running app comes out. v0 operates the Sandbox, dev server, and preview behind it. When you're ready, deploy to Vercel in one API call. v0 manages the whole pipeline. The new API lets you run v0's app builder inside your own product or pipeline. This opens use cases like: Below, we break down the API primitives behind this workflow. Each…
