## 🔧 Usage Instructions

### 🚀 Quick Start

The most recommended way to use AIClient2API is to start it through an automated script and configure it visually directly in the **Web UI console**.

#### 🐳 Docker Quick Start (Recommended)

```bash
docker run -d -p 3000:3000 -p 8086:8086 -p 1455:1455 -p 56121:56121 -p 19876-19880:19876-19880 --restart=always -v "your_path/configs:/app/configs" -v "your_path/plugins:/app/src/plugins-user" --name aiclient2api justlikemaki/aiclient-2-api
```

**Parameter Description**:
- `-d`: Run container in background
- `-p 3000:3000 ...`: Port mapping. 3000 is for Web UI, others are for OAuth callbacks (Antigravity: 8086, Codex: 1455, Grok CLI: 56121, Kiro: 19876-19880)
- `--restart=always`: Container auto-restart policy
- `-v "your_path/configs:/app/configs"`: Mount configuration directory (replace "your_path" with actual path, e.g., `/home/user/aiclient2api`)
- `-v "your_path/plugins:/app/src/plugins-user"`: Mount user plugins directory
- `--name aiclient2api`: Container name

#### 🐳 Docker Compose Deployment

You can also use Docker Compose for deployment. First, navigate to the `docker` directory:

```bash
cd docker
mkdir -p configs
docker compose up -d
```

To build from source instead of using the pre-built image, edit `docker-compose.yml`:
1. Comment out the `image: justlikemaki/aiclient-2-api:latest` line
2. Uncomment the `build:` section
3. Run `docker compose up -d --build`

#### 1. Run the startup script
*   **Linux/macOS**: `chmod +x install-and-run.sh && ./install-and-run.sh`
*   **Windows**: Double-click `install-and-run.bat`

> **💡 Manual installation and startup (supports custom parameters):**
> ```bash
> npm install
> # Default startup
> npm start
> # Show help information
> npm run help
> # Show API calling examples
> npm run example:api
> # Backend-only mode (disable frontend management UI)
> npm start -- --no-ui
> ```

#### 2. Access the console
After the server starts, open your browser and visit:
👉 [**http://localhost:3000**](http://localhost:3000)

> **Default Password**: `admin123` (can be changed in the console or by modifying the `pwd` file after login)

#### 3. Visual Configuration (Recommended)
Go to the **"Configuration"** page, you can:
*   ✅ Fill in the API Key for each provider or upload OAuth credential files
*   ✅ Switch default model providers in real-time
*   ✅ Monitor health status and real-time request logs

#### 4. Local Environment Preparation (Non-Docker Users)s
If you are running directly on your local machine (via script or Node.js) and need to bypass TLS detection for services like Grok, please ensure:
*   ✅ **Install Go Language**: Go to the [official Go website](https://go.dev/) to download and install (1.20+).
*   ✅ **Manually Compile Sidecar**: Execute the following command to compile the TLS proxy component:
    ```bash
    cd tls-sidecar && go build -o tls-sidecar && cd ..
    ```
    *Note: If this binary file is not compiled, the TLS Sidecar feature will fail to start as it cannot find the executable.*

**Claude-compatible (`/v1/messages`)**:
```bash
curl http://localhost:3000/claude-kiro-oauth/v1/messages \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-api-key" \
  -d '{
    "model": "claude-sonnet-4-5",
    "max_tokens": 1024,
    "thinking": { "type": "enabled", "budget_tokens": 10000 },
    "messages": [{ "role": "user", "content": "Solve this step by step." }]
  }'
```

**OpenAI-compatible (`/v1/chat/completions`)**:
```bash
curl http://localhost:3000/claude-kiro-oauth/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-api-key" \
  -d '{
    "model": "claude-sonnet-4-5",
    "messages": [{ "role": "user", "content": "Solve this step by step." }],

1. **Web UI Configuration** (Recommended): Convenient configuration management

In the "Configuration" page of the Web UI, you can visually configure all proxy options:
  - **Unified Proxy**: Fill in the proxy address in the "Proxy Settings" area and check the providers that need to use the proxy
  - **Provider Endpoints**: In each provider's configuration area, directly modify the Base URL to a proxied endpoint
  - **Click "Save Configuration"**: Takes effect immediately without restarting the service

2. **Unified Proxy Configuration**: Configure a global proxy and specify which providers use it

- **Web UI Configuration**: Fill in the proxy address in the "Proxy Settings" area of the "Configuration" page and check the providers that need to use the proxy
   - **Configuration File**: Configure in `configs/config.json`
   ```json
   {
     "PROXY_URL": "http://127.0.0.1:7890",
      "PROXY_ENABLED_PROVIDERS": [
        "gemini-antigravity",
        "claude-kiro-oauth",
        "grok-web"
      ]
    }
    ```

3. **Provider-Specific Proxied Endpoints**: Some providers (like OpenAI, Claude) support configuring proxied API endpoints

- **Web UI Configuration**: In each provider's configuration area on the "Configuration" page, modify the corresponding Base URL
   - **Configuration File**: Configure in `configs/config.json`
   ```json
   {
     "OPENAI_BASE_URL": "https://your-proxy-endpoint.com/v1",
     "CLAUDE_BASE_URL": "https://your-proxy-endpoint.com/v1"
   }
   ```

**Supported Proxy Types**:
- **HTTP Proxy**: `http://127.0.0.1:7890`
- **HTTPS Proxy**: `https://127.0.0.1:7890`
- **SOCKS5 Proxy**: `socks5://127.0.0.1:1080`

**Use Cases**:
- **Network-Restricted Environments**: Use in network environments where Google, OpenAI, and other services cannot be accessed directly
- **Hybrid Configuration**: Some providers use unified proxy, others use their own proxied endpoints
- **Flexible Switching**: Enable/disable proxy for specific providers at any time in the Web UI

**Notes**:
- Proxy configuration priority: Unified proxy configuration > Provider-specific endpoints > Direct connection
- Ensure the proxy service is stable and available, otherwise it may affect service quality
- SOCKS5 proxy usually performs better than HTTP proxy

#### 2. Model Filtering Configuration

Support excluding unsupported models through `notSupportedModels` configuration, the system will automatically skip these providers.

**Configuration**: Add `notSupportedModels` field for providers in `configs/provider_pools.json`:

```json
{
  "gemini-antigravity": [
    {
      "uuid": "provider-1",
      "notSupportedModels": ["gemini-3.0-pro", "gemini-3.5-flash"],
      "checkHealth": true
    }
  ]
}
```

**How It Works**:
- When requesting a specific model, the system automatically filters out providers that have configured the model as unsupported
- Only providers that support the model will be selected to handle the request

**Use Cases**:
- Some accounts cannot access specific models due to quota or permission restrictions
- Need to assign different model access permissions to different accounts

#### 3. Cross-Type Fallback Configuration

When all accounts under a Provider Type (e.g., `claude-kiro-oauth`) are exhausted due to 429 quota limits or marked as unhealthy, the system can automatically fallback to another compatible Provider Type (e.g., `claude-custom`) instead of returning an error directly.

**Configuration**: Add `providerFallbackChain` configuration in `configs/config.json`:

```json
{
  "providerFallbackChain": {
    "claude-kiro-oauth": ["claude-custom"],
    "claude-custom": ["claude-kiro-oauth"]
  }
}
```

**How It Works**:
1. Try to select a healthy account from the primary Provider Type pool
2. If all accounts in that type are unhealthy or return 429:
   - Look up the configured fallback types
   - Check if the fallback type supports the requested model (protocol compatibility check)
   - Select a healthy account from the fallback type's pool
3. Supports multi-level degradation chains: `claude-kiro-oauth → claude-custom → openai-custom`
4. Only returns an error if all fallback types are also unavailable

**Use Cases**:
- In batch task scenarios, the free RPD quota of a single Provider Type can be easily exhausted in a short time
- Through cross-type Fallback, you can fully utilize the independent quotas of multiple Providers, improving overall availability and throughput

**Notes**:
- Fallback only occurs between protocol-compatible types (e.g., between `gemini-*`, between `claude-*`)
- The system automatically checks if the target Provider Type supports the requested model

#### 4. TLS Sidecar (Bypass 403/Cloudflare)

For services like Grok that strictly validate TLS fingerprints (JA3/JA4), this project integrates a Sidecar proxy based on Go uTLS, which effectively solves 403 Forbidden errors by simulating browser TLS features.

**Configuration Instructions**:

1.  **Compile the Binary**:
    Since TLS simulation requires Go language support, you need to compile the sidecar first:
    ```bash
    cd tls-sidecar
    go build -o tls-sidecar
    ```
    *Windows users, after compiling, ensure the generated `tls-sidecar.exe` is located in the `tls-sidecar/` or the root directory.*

2.  **Enable Configuration**:
    Enable **TLS Sidecar** in the "Configuration" page of the Web UI, or modify `configs/config.json`:
    ```json
    {
      "TLS_SIDECAR_ENABLED": true,
      "TLS_SIDECAR_PORT": 9090
    }
    ```

3.  **How It Works**:
    - When enabled, the system automatically starts and manages the Go process.
    - Requests for specific providers (like Grok) are automatically routed to the Sidecar.
    - The Sidecar uses the latest Chrome fingerprint for TLS handshakes and supports automatic HTTP/2 negotiation.

**Notes**:
- Local running requires a Go environment (1.20+).
- **Docker Users**: The image already includes the pre-compiled binary; just enable it in the configuration, no manual compilation required.

## ❓ FAQ

<details>
<summary>Click to expand FAQ and solutions (port occupation, Docker startup, 429 errors, etc.)</summary>

### 1. OAuth Authorization Failed

**Problem Description**: After clicking "Generate Authorization", the browser opens the authorization page but authorization fails or cannot be completed.

**Solutions**:
- **Check Network Connection**: Ensure you can access Google, Alibaba Cloud, and other services normally
- **Check Port Occupation**: OAuth callbacks require specific ports (Antigravity: 8086, Codex: 1455, Grok CLI: 56121, Kiro: 19876-19880), ensure these ports are not occupied
- **Clear Browser Cache**: Try using incognito mode or clearing browser cache and retry
- **Check Firewall Settings**: Ensure the firewall allows access to local callback ports
- **Docker Users**: Ensure all OAuth callback ports are correctly mapped

### 2. Port Already in Use

**Problem Description**: When starting the service, it shows the port is already in use (e.g., `EADDRINUSE`).

**Solutions**:
```bash
# Windows - Find the process occupying the port
netstat -ano | findstr :3000
# Then use Task Manager to end the corresponding PID process

# Linux/macOS - Find and end the process occupying the port
lsof -i :3000
kill -9 <PID>
```

Or modify the port configuration in `configs/config.json` to use a different port.

### 3. Docker Container Won't Start

**Problem Description**: Docker container fails to start or exits immediately.

**Solutions**:
- **Check Logs**: `docker logs aiclient2api` to view error messages
- **Check Mount Path**: Ensure the local path in the `-v` parameter exists and has read/write permissions
- **Check Port Conflicts**: Ensure all mapped ports are not occupied on the host
- **Re-pull Image**: `docker pull justlikemaki/aiclient-2-api:latest`

### 4. Credential File Not Recognized

**Problem Description**: After uploading or configuring credential files, the system shows it cannot be recognized or format error.

**Solutions**:
- **Check File Format**: Ensure the credential file is valid JSON format
- **Check File Path**: Ensure the file path is correct, Docker users need to ensure the file is in the mounted directory
- **Check File Permissions**: Ensure the service has permission to read the credential file
- **Regenerate Credentials**: If credentials have expired, try re-authorizing via OAuth

### 5. Request Returns 429 Error

**Problem Description**: API requests frequently return 429 Too Many Requests error.

**Solutions**:
- **Configure Account Pool**: Add multiple accounts to `provider_pools.json`, enable polling mechanism
- **Configure Fallback**: Configure `providerFallbackChain` in `config.json` for cross-type degradation
- **Enable 429 Cooldown**: Set `RATE_LIMIT_COOLDOWN_ENABLED` to `true` and tune `RATE_LIMIT_COOLDOWN_MS` so rate-limited accounts temporarily leave the pool and recover automatically
- **Reduce Request Frequency**: Appropriately increase request intervals to avoid triggering rate limits
- **Wait for Quota Reset**: Free quotas usually reset daily or per minute

### 6. Model Unavailable or Returns Error

**Problem Description**: When requesting a specific model, it returns an error or shows the model is unavailable.

**Solutions**:
- **Check Model Name**: Ensure you're using the correct model name (case-sensitive)
- **Check Provider Support**: Confirm the currently configured provider supports that model
- **Check Account Permissions**: Some advanced models may require specific account permissions
- **Configure Model Filtering**: Use `notSupportedModels` to exclude unsupported models

### 7. Web UI Cannot Be Accessed

**Problem Description**: Browser cannot open `http://localhost:3000`.

**Solutions**:
- **Check Service Status**: Confirm the service has started successfully, check terminal output
- **Check Port Mapping**: Docker users ensure `-p 3000:3000` parameter is correct
- **Try Other Address**: Try accessing `http://127.0.0.1:3000`
- **Check Firewall**: Ensure the firewall allows access to port 3000

### 8. Streaming Response Interrupted

**Problem Description**: When using streaming output, the response is interrupted midway or incomplete.

**Solutions**:
- **Check Network Stability**: Ensure network connection is stable
- **Increase Timeout**: Increase request timeout in client configuration
- **Check Proxy Settings**: If using a proxy, ensure the proxy supports long connections
- **Check Service Logs**: Check for error messages

### 9. Configuration Changes Not Taking Effect

**Problem Description**: After modifying configuration in Web UI, service behavior doesn't change.

**Solutions**:
- **Refresh Page**: Refresh the Web UI page after modification
- **Check Save Status**: Confirm the configuration was saved successfully (check prompt messages)
- **Restart Service**: Some configurations may require service restart to take effect
- **Check Configuration File**: Directly check `configs/config.json` to confirm changes were written

### 10. API Returns 404

**Solutions**:
- **Check Endpoint Path**: Ensure you're using the correct endpoint path, such as `/v1/chat/completions` etc.
- **Check Client Auto-completion**: Some clients (like Cherry-Studio, NextChat) automatically append paths (like `/v1/chat/completions`) after the Base URL, causing path duplication. Check the actual request URL in the console and remove redundant path parts
- **Check Service Status**: Confirm the service has started normally, visit `http://localhost:3000` to view Web UI
- **Check Port Configuration**: Ensure requests are sent to the correct port (default 3000)
- **View Available Routes**: Check "Interactive Routing Examples" on the Web UI dashboard page to see all available endpoints

### 11. Unauthorized: API key is invalid or missing

**Problem Description**: When calling API endpoints, it returns `Unauthorized: API key is invalid or missing.` error.

**Solutions**:
- **Check API Key Configuration**: Ensure API Key is correctly configured in `configs/config.json` or Web UI
- **Check Request Header Format**: Ensure the request contains the correct Authorization header format, such as `Authorization: Bearer your-api-key`
- **Check Service Logs**: View detailed error messages on the "Real-time Logs" page in Web UI to locate the specific cause

### 12. No available and healthy providers for type

**Problem Description**: When calling API, it returns `No available and healthy providers for type xxx` error.

**Solutions**:
- **Check Provider Status**: Check if providers of the corresponding type are in healthy status on the "Provider Pools" page in Web UI
- **Check Credential Validity**: Confirm OAuth credentials have not expired; if expired, regenerate authorization
- **Check Quota Limits**: Some providers may have reached free quota limits; wait for quota reset or add more accounts
- **Enable Fallback**: Configure `providerFallbackChain` in `config.json` to automatically switch to backup providers when the primary provider is unavailable
- **View Detailed Logs**: Check specific health check failure reasons on the "Real-time Logs" page in Web UI

### 13. Request Returns 403 Forbidden Error

**Problem Description**: API requests return 403 Forbidden error.

**Solutions**:
- **Enable TLS Sidecar**: For services like Grok, 403 is often due to TLS fingerprint blocking. Please refer to [Advanced Configuration - TLS Sidecar](#5-tls-sidecar-bypass-403cloudflare) to enable and compile the Sidecar.
- **Check Node Status**: If you see the node status is normal (health check passed) on the "Provider Pools" page in Web UI, you can ignore this error as the system will handle it automatically
- **Check Account Permissions**: Confirm the account has permission to access the requested model or service
- **Check API Key Permissions**: Some providers' API Keys may have access scope restrictions; ensure the Key has sufficient permissions
- **Check Regional Restrictions**: Some services may have regional access restrictions; try using a proxy or VPN
- **Check Credential Status**: OAuth credentials may have been revoked or expired; try regenerating authorization
- **Check Request Frequency**: Some providers have strict request frequency limits; reduce request frequency and retry
- **View Provider Documentation**: Visit the official documentation of the corresponding provider to understand specific access restrictions and requirements

### 14. Why should I enable "OAuth Token Auto-Refresh"?

**Problem Description**: Unsure if token auto-refresh is necessary.

**Solution**:
OAuth tokens (e.g., Gemini, Antigravity, Codex) typically have a limited lifespan (e.g., 1 hour).
- **With it enabled**: The system automatically checks and refreshes tokens before they expire in the background. This ensures 24/7 stable API service and avoids `401 Unauthorized` or `403 Forbidden` errors due to expired tokens.
- **Without it**: Once a token expires, the system cannot automatically obtain a new one, causing API requests to fail until you manually re-authorize.

### 15. What is the impact of not enabling "Preload Model Providers" on token maintenance?

**Problem Description**: Confusion about the "Preload Model Providers" configuration and its relation to token refresh.

**Solution**:
The system only performs auto-refresh tasks for providers that are **loaded into the active pool**.
- **Impact**: If a provider is not checked as a "Preload Model Provider" in the configuration, it won't be initialized when the system starts. Since it's not in the pool, the background refresh task will **not** process its token.
- **Consequence**: If you don't use that provider for a long time, its token will expire silently. When you eventually call it via a specific route, the request will fail due to the expired token.
- **Recommendation**: Always check providers you intend to use frequently and need to keep active in the "Preload Model Providers" list.
