## 🤔 Why 9Router?

**Stop wasting money and hitting limits:**

- ❌ Subscription quota expires unused every month
- ❌ Rate limits stop you mid-coding
- ❌ Expensive APIs ($20-50/month per provider)
- ❌ Manual switching between providers

**9Router solves this:**

- ✅ **Maximize subscriptions** - Track quota, use every bit before reset
- ✅ **Auto fallback** - Subscription → Cheap → Free, zero downtime
- ✅ **Multi-account** - Round-robin between accounts per provider
- ✅ **Universal** - Works with Claude Code, Codex, Gemini CLI, Cursor, Cline, any CLI tool

## ⚡ Quick Start

**1. Install globally:**

```bash
npm install -g 9router
9router
```

🎉 Dashboard opens at `http://localhost:20128`

**2. Connect a FREE provider (no signup needed):**

Dashboard → Providers → Connect **Claude Code** or **Antigravity** → OAuth login → Done!

**3. Use in your CLI tool:**

```
Claude Code/Codex/Gemini CLI/OpenClaw/Cursor/Cline Settings:
  Endpoint: http://localhost:20128/v1
  API Key: [copy from dashboard]
  Model: if/kimi-k2-thinking
```

**That's it!** Start coding with FREE AI models.

**Alternative: run from source (this repository):**

This repository package is private (`9router-app`), so source/Docker execution is the expected local development path.

```bash
cp .env.example .env
npm install
PORT=20128 NEXT_PUBLIC_BASE_URL=http://localhost:20128 npm run dev
```

Production mode:

```bash
npm run build
PORT=20128 HOSTNAME=0.0.0.0 NEXT_PUBLIC_BASE_URL=http://localhost:20128 npm run start
```

Default URLs:
- Dashboard: `http://localhost:20128/dashboard`
- OpenAI-compatible API: `http://localhost:20128/v1`

### 🎯 Smart 3-Tier Fallback

Create combos with automatic fallback:

```
Combo: "my-coding-stack"
  1. cc/claude-opus-4-6        (your subscription)
  2. glm/glm-4.7               (cheap backup, $0.6/1M)
  3. if/kimi-k2-thinking       (free fallback)

→ Auto switches when quota runs out or errors occur
```

### 📊 Real-Time Quota Tracking

- Token consumption per provider
- Reset countdown (5-hour, daily, weekly)
- Cost estimation for paid tiers
- Monthly spending reports

### 🔄 Format Translation

Seamless translation between formats:
- **OpenAI** ↔ **Claude** ↔ **Gemini** ↔ **OpenAI Responses**
- Your CLI tool sends OpenAI format → 9Router translates → Provider receives native format
- Works with any tool that supports custom OpenAI endpoints

### 👥 Multi-Account Support

- Add multiple accounts per provider
- Auto round-robin or priority-based routing
- Fallback to next account when one hits quota

### 🔄 Auto Token Refresh

- OAuth tokens automatically refresh before expiration
- No manual re-authentication needed
- Seamless experience across all providers

### 🎨 Custom Combos

- Create unlimited model combinations
- Mix subscription, cheap, and free tiers
- Name your combos for easy access
- Share combos across devices with Cloud Sync

### 📝 Request Logging

- Enable debug mode for full request/response logs
- Track API calls, headers, and payloads
- Troubleshoot integration issues
- Export logs for analysis

### 💾 Cloud Sync

- Sync providers, combos, and settings across devices
- Automatic background sync
- Secure encrypted storage
- Access your setup from anywhere

#### Cloud Runtime Notes

- Prefer server-side cloud variables in production:
  - `BASE_URL` (internal callback URL used by sync scheduler)
  - `CLOUD_URL` (cloud sync endpoint base)
- `NEXT_PUBLIC_BASE_URL` and `NEXT_PUBLIC_CLOUD_URL` are still supported for compatibility/UI, but server runtime now prioritizes `BASE_URL`/`CLOUD_URL`.
- Cloud sync requests now use timeout + fail-fast behavior to avoid UI hanging when cloud DNS/network is unavailable.

### 📊 Usage Analytics

- Track token usage per provider and model
- Cost estimation and spending trends
- Monthly reports and insights
- Optimize your AI spending

### 🌐 Deploy Anywhere

- 💻 **Localhost** - Default, works offline
- ☁️ **VPS/Cloud** - Share across devices
- 🐳 **Docker** - One-command deployment
- 🚀 **Cloudflare Workers** - Global edge network

    "defaults": {
      "model": {
        "primary": "9router/if/glm-4.7"
      }
    }
  },
  "models": {
    "providers": {
      "9router": {
        "baseUrl": "http://127.0.0.1:20128/v1",
        "apiKey": "sk_9router",
        "api": "openai-completions",

| `INITIAL_PASSWORD` | `123456` | First login password when no saved hash exists |
| `DATA_DIR` | `~/.9router` | Main app database location (`db.json`) |
| `PORT` | framework default | Service port (`20128` in examples) |
| `HOSTNAME` | framework default | Bind host (Docker defaults to `0.0.0.0`) |
| `NODE_ENV` | runtime default | Set `production` for deploy |
| `BASE_URL` | `http://localhost:20128` | Server-side internal base URL used by cloud sync jobs |
| `CLOUD_URL` | `https://9router.com` | Server-side cloud sync endpoint base URL |
| `NEXT_PUBLIC_BASE_URL` | `http://localhost:3000` | Backward-compatible/public base URL (prefer `BASE_URL` for server runtime) |
| `NEXT_PUBLIC_CLOUD_URL` | `https://9router.com` | Backward-compatible/public cloud URL (prefer `CLOUD_URL` for server runtime) |
| `API_KEY_SECRET` | `endpoint-proxy-api-key-secret` | HMAC secret for generated API keys |

| `HTTP_PROXY`, `HTTPS_PROXY`, `ALL_PROXY`, `NO_PROXY` | empty | Optional outbound proxy for upstream provider calls |

Notes:
- Lowercase proxy variables are also supported: `http_proxy`, `https_proxy`, `all_proxy`, `no_proxy`.
- `.env` is not baked into Docker image (`.dockerignore`); inject runtime config with `--env-file` or `-e`.
- On Windows, `APPDATA` can be used for local storage path resolution.
- `INSTANCE_NAME` appears in older docs/env templates, but is currently not used at runtime.

### Runtime Files and Storage

- Main app state: `${DATA_DIR}/db.json` (providers, combos, aliases, keys, settings), managed by `src/lib/localDb.js`.
- Usage history and logs: `~/.9router/usage.json` and `~/.9router/log.txt`, managed by `src/lib/usageDb.js`.
- Optional request/translator logs: `<repo>/logs/...` when `ENABLE_REQUEST_LOGS=true`.
- Usage storage currently follows `~/.9router` path logic and is independent from `DATA_DIR`.

## 🐛 Troubleshooting

**"Language model did not provide messages"**
- Provider quota exhausted → Check dashboard quota tracker
- Solution: Use combo fallback or switch to cheaper tier

**Rate limiting**
- Subscription quota out → Fallback to GLM/MiniMax
- Add combo: `cc/claude-opus-4-6 → glm/glm-4.7 → if/kimi-k2-thinking`

**OAuth token expired**
- Auto-refreshed by 9Router
- If issues persist: Dashboard → Provider → Reconnect

**High costs**
- Check usage stats in Dashboard
- Switch primary model to GLM/MiniMax
- Use free tier (Gemini CLI, iFlow) for non-critical tasks

**Dashboard opens on wrong port**
- Set `PORT=20128` and `NEXT_PUBLIC_BASE_URL=http://localhost:20128`

**Cloud sync errors**
- Verify `BASE_URL` points to your running instance (example: `http://localhost:20128`)
- Verify `CLOUD_URL` points to your expected cloud endpoint (example: `https://9router.com`)
- Keep `NEXT_PUBLIC_*` values aligned with server-side values when possible.

**Cloud endpoint `stream=false` returns 500 (`Unexpected token 'd'...`)**
- Symptom usually appears on public cloud endpoint (`https://9router.com/v1`) for non-streaming calls.
- Root cause: upstream returns SSE payload (`data: ...`) while client expects JSON.
- Workaround: use `stream=true` for cloud direct calls.
- Local 9Router runtime includes SSE→JSON fallback for non-streaming calls when upstream returns `text/event-stream`.

**Cloud says connected, but request still fails with `Invalid API key`**
- Create a fresh key from local dashboard (`/api/keys`) and run cloud sync (`Enable Cloud` then `Sync Now`).
- Old/non-synced keys can still return `401` on cloud even if local endpoint works.

**First login not working**
- Check `INITIAL_PASSWORD` in `.env`
- If unset, fallback password is `123456`

**No request logs under `logs/`**
- Set `ENABLE_REQUEST_LOGS=true`

## 📝 API Reference

### Chat Completions

```bash
POST http://localhost:20128/v1/chat/completions
Authorization: Bearer your-api-key
Content-Type: application/json

{
  "model": "cc/claude-opus-4-6",
  "messages": [
    {"role": "user", "content": "Write a function to..."}
  ],
  "stream": true
}
```

### List Models

```bash
GET http://localhost:20128/v1/models
Authorization: Bearer your-api-key

→ Returns all models + combos in OpenAI format
```

### Compatibility Endpoints

- `POST /v1/chat/completions`
- `POST /v1/messages`
- `POST /v1/responses`
- `GET /v1/models`
- `POST /v1/messages/count_tokens`
- `GET /v1beta/models`

### Cloud Validation Scripts

Added test scripts under `tester/security/`:

- `tester/security/test-docker-hardening.sh`
  - Builds Docker image and validates hardening checks (`/api/cloud/auth` auth guard, `REQUIRE_API_KEY`, secure auth cookie behavior).
- `tester/security/test-cloud-openai-compatible.sh`
  - Sends a direct OpenAI-compatible request to cloud endpoint (`https://9router.com/v1/chat/completions`) with provided model/key.
- `tester/security/test-cloud-sync-and-call.sh`
  - End-to-end flow: create local key -> enable/sync cloud -> call cloud endpoint with retry.
  - Includes fallback check with `stream=true` to distinguish auth errors from non-streaming parse issues.

Security note for cloud test scripts:

- Never hardcode real API keys in scripts/commits.
- Provide keys only via environment variables:
  - `API_KEY`, `CLOUD_API_KEY`, or `OPENAI_API_KEY` (supported by `test-cloud-openai-compatible.sh`)
- Example:

```bash
OPENAI_API_KEY="your-cloud-key" bash tester/security/test-cloud-openai-compatible.sh
```

Expected behavior from recent validation:

- Local runtime (`http://127.0.0.1:20128/v1/chat/completions`): works with `stream=false` and `stream=true`.
- Docker runtime (same API path exposed by container): hardening checks pass, cloud auth guard works, strict API key mode works when enabled.
- Public cloud endpoint (`https://9router.com/v1/chat/completions`):
  - `stream=true`: expected to succeed (SSE chunks returned).
  - `stream=false`: may fail with `500` + parse error (`Unexpected token 'd'`) when upstream returns SSE content to a non-streaming client path.

### Dashboard and Management API

- Auth/settings: `/api/auth/login`, `/api/auth/logout`, `/api/settings`, `/api/settings/require-login`
- Provider management: `/api/providers`, `/api/providers/[id]`, `/api/providers/[id]/test`, `/api/providers/[id]/models`, `/api/providers/validate`, `/api/provider-nodes*`
- OAuth flows: `/api/oauth/[provider]/[action]` (+ provider-specific imports like Cursor/Kiro)
- Routing config: `/api/models/alias`, `/api/combos*`, `/api/keys*`, `/api/pricing`
- Usage/logs: `/api/usage/history`, `/api/usage/logs`, `/api/usage/request-logs`, `/api/usage/[connectionId]`
- Cloud sync: `/api/sync/cloud`, `/api/sync/initialize`, `/api/cloud/*`
- CLI helpers: `/api/cli-tools/claude-settings`, `/api/cli-tools/codex-settings`, `/api/cli-tools/droid-settings`, `/api/cli-tools/openclaw-settings`

### Authentication Behavior

- Dashboard routes (`/dashboard/*`) use `auth_token` cookie protection.
- Login uses saved password hash when present; otherwise it falls back to `INITIAL_PASSWORD`.
- `requireLogin` can be toggled via `/api/settings/require-login`.

### Request Processing (High Level)

1. Client sends request to `/v1/*`.
2. Route handler calls `handleChat` (`src/sse/handlers/chat.js`).
3. Model is resolved (direct provider/model or alias/combo resolution).
4. Credentials are selected from local DB with account availability filtering.
5. `handleChatCore` (`open-sse/handlers/chatCore.js`) detects format and translates request.
6. Provider executor sends upstream request.
7. Stream is translated back to client format when needed.
8. Usage/logging is recorded (`src/lib/usageDb.js`).
9. Fallback applies on provider/account/model errors according to combo rules.
