# 0x0 Server

> Local AI runtime for 0x0 clients.

`@anonymous-dev/0x0-server` is the local runtime for AI-powered developer tools.

It exposes one provider layer over OpenAI and Anthropic models. The primary app surfaces
are server chat and server completions. Clients can call them through HTTP for simple
requests or WebSocket for editor sessions, agent turns, cancellation, and change review.

## What It Provides

* Provider discovery through `GET /providers`
* Streaming chat through `POST /chat`
* One-shot code completion through `POST /completions`
* One-shot inline edits through `POST /inline-edit`
* Git-backed agent sessions over `/ws`
* Worktree-based change review with accept and discard operations

## Quick Start

```bash theme={null}
# from the 0x0 repo
bun install

OPENAI_API_KEY=... ANTHROPIC_API_KEY=... bun run --cwd apps/server dev
```

The server listens on `http://127.0.0.1:4096` by default. Set `PORT` to choose another
port.

| WebSocket | Editor sessions, long-running agent turns, cancellation, and review state |
| Worktrees | Isolated agent edits before the user accepts or discards changes          |
