## 🎯 Use Cases

### Case 1: "I have Claude Pro subscription"

**Problem:** Quota expires unused, rate limits during heavy coding

```
Combo: "maximize-claude"
  1. cc/claude-opus-4-6        (use subscription fully)
  2. glm/glm-4.7               (cheap backup when quota out)
  3. if/kimi-k2-thinking       (free emergency fallback)

Monthly cost: $20 (subscription) + ~$5 (backup) = $25 total
vs. $20 + hitting limits = frustration
```

### Case 2: "I want zero cost"

**Problem:** Can't afford subscriptions, need reliable AI coding

```
Combo: "free-forever"
  1. gc/gemini-3-flash         (180K free/month)
  2. if/kimi-k2-thinking       (unlimited free)
  3. qw/qwen3-coder-plus       (unlimited free)

Monthly cost: $0
Quality: Production-ready models
```

### Case 3: "I need 24/7 coding, no interruptions"

**Problem:** Deadlines, can't afford downtime

```
Combo: "always-on"
  1. cc/claude-opus-4-6        (best quality)
  2. cx/gpt-5.2-codex          (second subscription)
  3. glm/glm-4.7               (cheap, resets daily)
  4. minimax/MiniMax-M2.1      (cheapest, 5h reset)
  5. if/kimi-k2-thinking       (free unlimited)

Result: 5 layers of fallback = zero downtime
Monthly cost: $20-200 (subscriptions) + $10-20 (backup)
```

### Case 4: "I want FREE AI in OpenClaw"

**Problem:** Need AI assistant in messaging apps, completely free

```
Combo: "openclaw-free"
  1. if/glm-4.7                (unlimited free)
  2. if/minimax-m2.1           (unlimited free)
  3. if/kimi-k2-thinking       (unlimited free)

Monthly cost: $0
Access via: WhatsApp, Telegram, Slack, Discord, iMessage, Signal...

---

## 🚀 Deployment

### Global npm install (Recommended)

```bash
npm install -g omniroute

# Create config directory
mkdir -p ~/.omniroute

# Create .env file (see .env.example)
cp .env.example ~/.omniroute/.env

# Start server
omniroute
# Or with custom port:
omniroute --port 3000
```

The CLI automatically loads `.env` from `~/.omniroute/.env` or `./.env`.

### VPS Deployment

```bash
git clone https://github.com/diegosouzapw/OmniRoute.git
cd OmniRoute && npm install && npm run build

export JWT_SECRET="your-secure-secret-change-this"
export INITIAL_PASSWORD="your-password"
export DATA_DIR="/var/lib/omniroute"
export PORT="20128"
export HOSTNAME="0.0.0.0"
export NODE_ENV="production"
export NEXT_PUBLIC_BASE_URL="http://localhost:20128"
export API_KEY_SECRET="endpoint-proxy-api-key-secret"

npm run start
# Or: pm2 start npm --name omniroute -- start
```

### PM2 Deployment (Low Memory)

For servers with limited RAM, use the memory limit option:

```bash
# With 512MB limit (default)
pm2 start npm --name omniroute -- start

# Or with custom memory limit
OMNIROUTE_MEMORY_MB=512 pm2 start npm --name omniroute -- start

# Or using ecosystem.config.js
pm2 start ecosystem.config.js
```

Create `ecosystem.config.js`:

```javascript
module.exports = {
  apps: [
    {
      name: "omniroute",
      script: "npm",
      args: "start",
      env: {
        NODE_ENV: "production",
        OMNIROUTE_MEMORY_MB: "512",
        JWT_SECRET: "your-secret",
        INITIAL_PASSWORD: "your-password",
      },
      node_args: "--max-old-space-size=512",
      max_memory_restart: "300M",
    },
  ],
};
```

### Docker

```bash
# Build image (default = runner-cli with codex/claude/droid preinstalled)
docker build -t omniroute:cli .

# Portable mode (recommended)
docker run -d --name omniroute -p 20128:20128 --env-file ./.env -v omniroute-data:/app/data omniroute:cli
```

For host-integrated mode with CLI binaries, see the Docker section in the main docs.

## 🧩 Advanced Features

### Custom Models

Add any model ID to any provider without waiting for an app update:

```bash
# Via API
curl -X POST http://localhost:20128/api/provider-models \
  -H "Content-Type: application/json" \
  -d '{"provider": "openai", "modelId": "gpt-4.5-preview", "modelName": "GPT-4.5 Preview"}'

# List: curl http://localhost:20128/api/provider-models?provider=openai
# Remove: curl -X DELETE "http://localhost:20128/api/provider-models?provider=openai&model=gpt-4.5-preview"
```

Or use Dashboard: **Providers → [Provider] → Custom Models**.

### Dedicated Provider Routes

Route requests directly to a specific provider with model validation:

```bash
POST http://localhost:20128/v1/providers/openai/chat/completions
POST http://localhost:20128/v1/providers/openai/embeddings
POST http://localhost:20128/v1/providers/fireworks/images/generations
```

The provider prefix is auto-added if missing. Mismatched models return `400`.

### Network Proxy Configuration

```bash
# Set global proxy
curl -X PUT http://localhost:20128/api/settings/proxy \
  -d '{"global": {"type":"http","host":"proxy.example.com","port":"8080"}}'

# Per-provider proxy
curl -X PUT http://localhost:20128/api/settings/proxy \
  -d '{"providers": {"openai": {"type":"socks5","host":"proxy.example.com","port":"1080"}}}'

# Test proxy
curl -X POST http://localhost:20128/api/settings/proxy/test \
  -d '{"proxy":{"type":"socks5","host":"proxy.example.com","port":"1080"}}'
```

**Precedence:** Key-specific → Combo-specific → Provider-specific → Global → Environment.

### Model Catalog API

```bash
curl http://localhost:20128/api/models/catalog
```

Returns models grouped by provider with types (`chat`, `embedding`, `image`).

### Cloud Sync

- Sync providers, combos, and settings across devices
- Automatic background sync with timeout + fail-fast
- Prefer server-side `BASE_URL`/`CLOUD_URL` in production

### LLM Gateway Intelligence (Phase 9)

- **Semantic Cache** — Auto-caches non-streaming, temperature=0 responses (bypass with `X-OmniRoute-No-Cache: true`)
- **Request Idempotency** — Deduplicates requests within 5s via `Idempotency-Key` or `X-Request-Id` header
- **Progress Tracking** — Opt-in SSE `event: progress` events via `X-OmniRoute-Progress: true` header

| Mode             | Purpose                                                                                |
| ---------------- | -------------------------------------------------------------------------------------- |
| **Playground**   | Select source/target formats, paste a request, and see the translated output instantly |
| **Chat Tester**  | Send live chat messages through the proxy and inspect the full request/response cycle  |
| **Test Bench**   | Run batch tests across multiple format combinations to verify translation correctness  |
| **Live Monitor** | Watch real-time translations as requests flow through the proxy                        |

**Use cases:**

- Debug why a specific client/provider combination fails
- Verify that thinking tags, tool calls, and system prompts translate correctly
- Compare format differences between OpenAI, Claude, Gemini, and Responses API formats

### Routing Strategies

Configure via **Dashboard → Settings → Routing**.

| Strategy                       | Description                                                                                      |
| ------------------------------ | ------------------------------------------------------------------------------------------------ |
| **Fill First**                 | Uses accounts in priority order — primary account handles all requests until unavailable         |
| **Round Robin**                | Cycles through all accounts with a configurable sticky limit (default: 3 calls per account)      |
| **P2C (Power of Two Choices)** | Picks 2 random accounts and routes to the healthier one — balances load with awareness of health |
| **Random**                     | Randomly selects an account for each request using Fisher-Yates shuffle                          |
| **Least Used**                 | Routes to the account with the oldest `lastUsedAt` timestamp, distributing traffic evenly        |
| **Cost Optimized**             | Routes to the account with the lowest priority value, optimizing for lowest-cost providers       |

#### External Sticky Session Header

For external session affinity (for example, Claude Code/Codex agents behind reverse proxies), send:

```http
X-Session-Id: your-session-key
```

OmniRoute also accepts `x_session_id` and returns the effective session key in `X-OmniRoute-Session-Id`.

If you use Nginx and send underscore-form headers, enable:

```nginx
underscores_in_headers on;
```

#### Wildcard Model Aliases

Create wildcard patterns to remap model names:

```
Pattern: claude-sonnet-*     →  Target: cc/claude-sonnet-4-5-20250929
Pattern: gpt-*               →  Target: gh/gpt-5.1-codex
```

Wildcards support `*` (any characters) and `?` (single character).

#### Fallback Chains

Define global fallback chains that apply across all requests:

```
Chain: production-fallback
  1. cc/claude-opus-4-6
  2. gh/gpt-5.1-codex
  3. glm/glm-4.7
```

---

### Resilience & Circuit Breakers

Configure via **Dashboard → Settings → Resilience**.

OmniRoute implements provider-level resilience with four components:

1. **Provider Profiles** — Per-provider configuration for:
   - Failure threshold (how many failures before opening)
   - Cooldown duration
   - Rate limit detection sensitivity
   - Exponential backoff parameters

2. **Editable Rate Limits** — System-level defaults configurable in the dashboard:
   - **Requests Per Minute (RPM)** — Maximum requests per minute per account
   - **Min Time Between Requests** — Minimum gap in milliseconds between requests
   - **Max Concurrent Requests** — Maximum simultaneous requests per account
   - Click **Edit** to modify, then **Save** or **Cancel**. Values persist via the resilience API.

3. **Circuit Breaker** — Tracks failures per provider and automatically opens the circuit when a threshold is reached:
   - **CLOSED** (Healthy) — Requests flow normally
   - **OPEN** — Provider is temporarily blocked after repeated failures
   - **HALF_OPEN** — Testing if provider has recovered

4. **Policies & Locked Identifiers** — Shows circuit breaker status and locked identifiers with force-unlock capability.

5. **Rate Limit Auto-Detection** — Monitors `429` and `Retry-After` headers to proactively avoid hitting provider rate limits.

**Pro Tip:** Use **Reset All** button to clear all circuit breakers and cooldowns when a provider recovers from an outage.

### Database Export / Import

Manage database backups in **Dashboard → Settings → System & Storage**.

| Action                   | Description                                                                                                                    |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------ |
| **Export Database**      | Downloads the current SQLite database as a `.sqlite` file                                                                      |
| **Export All (.tar.gz)** | Downloads a full backup archive including: database, settings, combos, provider connections (no credentials), API key metadata |
| **Import Database**      | Upload a `.sqlite` file to replace the current database. A pre-import backup is automatically created                          |

```bash
# API: Export database
curl -o backup.sqlite http://localhost:20128/api/db-backups/export

# API: Export all (full archive)
curl -o backup.tar.gz http://localhost:20128/api/db-backups/exportAll

# API: Import database
curl -X POST http://localhost:20128/api/db-backups/import \
  -F "file=@backup.sqlite"
```

**Import Validation:** The imported file is validated for integrity (SQLite pragma check), required tables (`provider_connections`, `provider_nodes`, `combos`, `api_keys`), and size (max 100MB).

**Use Cases:**

- Migrate OmniRoute between machines
- Create external backups for disaster recovery
- Share configurations between team members (export all → share archive)
