# 0x0 Server Chat

> Streaming chat, inline edits, agent sessions, and review.

Server chat is the conversational app surface in `@anonymous-dev/0x0-server`.

Use it for normal assistant chat, inline edit instructions, agent turns in an isolated
worktree, cancellation, and accepting or discarding generated changes.

## HTTP Chat

`POST /chat` sends a stateless chat request to a configured provider. It streams SSE by
default and can return a single JSON response when `stream` is `false`.

```bash theme={null}
curl -N -X POST http://localhost:4096/chat \
  -H "Content-Type: application/json" \
  -d '{
    "provider": "codex",
    "model": "gpt-5.4-mini",
    "messages": [{ "role": "user", "content": "Explain this module." }]
  }'
```

## Inline Edits

`POST /inline-edit` converts an instruction plus a selected range into replacement text.
Editor clients use it for focused changes where the checkout should stay under user
control.

## WebSocket Sessions

`/ws` is the session surface for long-running work:

| Message                | Purpose                                   |
| ---------------------- | ----------------------------------------- |
| `session.create`       | Create a git-backed agent session         |
| `session.open`         | Reopen an existing session                |
| `chat.turn`            | Run an agent turn in the session worktree |
| `run.cancel`           | Cancel an active run                      |
| `changes.status`       | Read changed files                        |
| `changes.accept_all`   | Apply all agent changes                   |
| `changes.discard_all`  | Drop all agent changes                    |
| `changes.accept_file`  | Apply one changed file                    |
| `changes.discard_file` | Drop one changed file                     |

The Neovim chat client and TUI both build on this surface.
