## Why Included

The generally available v0 API gives agents headless app generation with stateful chats, sandboxed execution, streamed traces, live previews, and one-call Vercel deployment.

## Source Summary

The **v0 API is generally available** for headless app building. Each chat is an isolated, stateful app workspace that can edit and run files in a Vercel Sandbox, expose a live preview, and accept follow-up changes through sync, async, or streaming calls.

## Practical Implication

Treat v0 as a bounded app-building tool inside a larger agent loop: retain one chat ID per app, stream ordered work parts into your UI, and proxy preview traffic server-side. Existing repos, ZIPs, or files can seed a chat, and up to **three skills per request** can supply design-system context.

## Agent-Ready Context

The **v0 API is generally available** for headless app building. Each chat is an isolated, stateful app workspace that can edit and run files in a Vercel Sandbox, expose a live preview, and accept follow-up changes through sync, async, or streaming calls.

Treat v0 as a bounded app-building tool inside a larger agent loop: retain one chat ID per app, stream ordered work parts into your UI, and proxy preview traffic server-side. Existing repos, ZIPs, or files can seed a chat, and up to **three skills per request** can supply design-system context.

Chats from the previous API do not run on the new version; migration requires exporting a chosen version as a ZIP and creating a new chat from it. Preview tokens are short-lived, and API keys must stay behind the server proxy.

## Connected Context

Feed7 judgment across 368 accumulated Signals:

This makes v0 a headless, stateful app-building component rather than another general coding-agent runtime: the host application owns chat-to-app identity, ordered UI rendering, preview proxying, and migration boundaries while v0 owns an isolated executable workspace. It strengthens the embedded-agent pattern but narrows it to app generation, with server-side key handling and expiring preview access as integration requirements.

- [How Notion used the Cursor SDK to embed coding agents](https://feed7.dev/p/notion-07d02so) — Both support embedding coding work inside another product, but v0 supplies an app-specific stateful workspace and live preview rather than the issue-to-PR workflow described by Notion.
- [github/copilot-sdk](https://feed7.dev/p/copilot-sdk-0vwjjou) — Copilot SDK exposes a configurable general agent runtime, while v0 offers a more bounded app-building service whose host must manage chat identity, previews, and migration.
- [Run Claude Managed Agents with Chat SDK](https://feed7.dev/p/claude-managed-agents-with-chat-sdk-0wtme2i) — Both retain execution state in a hosted agent service, but v0 adds an isolated runnable app workspace and preview while requiring the integrating application to proxy that preview.
- [Vercel Plugin now available in VS Code and GitHub Copilot CLI](https://feed7.dev/p/vercel-plugin-now-available-in-vs-code-and-github-copilot-cli-11mhomy) — The plugin supplies Vercel guidance to external coding agents; v0 instead accepts up to three skills as request-time context within its own app-building workspace.

## Uncertainty

- Chats from the previous API do not run on the new version; migration requires exporting a chosen version as a ZIP and creating a new chat from it. Preview tokens are short-lived, and API keys must stay behind the server proxy.
