# CLI Proxy API
English | [中文](README_CN.md)
A proxy server that provides OpenAI/Gemini/Claude/Codex compatible API interfaces for CLI.
It now also supports OpenAI Codex (GPT models) and Claude Code via OAuth.
So you can use local or multi-account CLI access with OpenAI(include Responses)/Gemini/Claude-compatible clients and SDKs.
The first Chinese provider has now been added: [Qwen Code](https://github.com/QwenLM/qwen-code).
## Features
- OpenAI/Gemini/Claude compatible API endpoints for CLI models
- OpenAI Codex support (GPT models) via OAuth login
- Claude Code support via OAuth login
- Qwen Code support via OAuth login
- Gemini Web support via cookie-based login
- Streaming and non-streaming responses
- Function calling/tools support
- Multimodal input support (text and images)
- Multiple accounts with round-robin load balancing (Gemini, OpenAI, Claude and Qwen)
- Simple CLI authentication flows (Gemini, OpenAI, Claude and Qwen)
- Generative Language API Key support
- Gemini CLI multi-account load balancing
- Claude Code multi-account load balancing
- Qwen Code multi-account load balancing
- OpenAI Codex multi-account load balancing
- OpenAI-compatible upstream providers via config (e.g., OpenRouter)
## Installation
### Prerequisites
- Go 1.24 or higher
- A Google account with access to Gemini CLI models (optional)
- An OpenAI account for Codex/GPT access (optional)
- An Anthropic account for Claude Code access (optional)
- A Qwen Chat account for Qwen Code access (optional)
### Building from Source
1. Clone the repository:
```bash
git clone https://github.com/luispater/CLIProxyAPI.git
cd CLIProxyAPI
```
2. Build the application:
Linux, macOS:
```bash
go build -o cli-proxy-api ./cmd/server
```
Windows:
```bash
go build -o cli-proxy-api.exe ./cmd/server
```
## Usage
### Authentication
You can authenticate for Gemini, OpenAI, and/or Claude. All can coexist in the same `auth-dir` and will be load balanced.
- Gemini (Google):
```bash
./cli-proxy-api --login
```
If you are an existing Gemini Code user, you may need to specify a project ID:
```bash
./cli-proxy-api --login --project_id <your_project_id>
```
The local OAuth callback uses port `8085`.
Options: add `--no-browser` to print the login URL instead of opening a browser. The local OAuth callback uses port `8085`.
- Gemini Web (via Cookies):
This method authenticates by simulating a browser, using cookies obtained from the Gemini website.
```bash
./cli-proxy-api --gemini-web-auth
```
You will be prompted to enter your `__Secure-1PSID` and `__Secure-1PSIDTS` values. Please retrieve these cookies from your browser's developer tools.
- OpenAI (Codex/GPT via OAuth):
```bash
./cli-proxy-api --codex-login
```
Options: add `--no-browser` to print the login URL instead of opening a browser. The local OAuth callback uses port `1455`.
- Claude (Anthropic via OAuth):
```bash
./cli-proxy-api --claude-login
```
Options: add `--no-browser` to print the login URL instead of opening a browser. The local OAuth callback uses port `54545`.
- Qwen (Qwen Chat via OAuth):
```bash
./cli-proxy-api --qwen-login
```
Options: add `--no-browser` to print the login URL instead of opening a browser. Use the Qwen Chat's OAuth device flow.
### Starting the Server
Once authenticated, start the server:
```bash
./cli-proxy-api
```
By default, the server runs on port 8317.
### API Endpoints
#### List Models
```
GET http://localhost:8317/v1/models
```
#### Chat Completions
```
POST http://localhost:8317/v1/chat/completions
```
Request body example:
```json
{
"model": "gemini-2.5-pro",
"messages": [
{
"role": "user",
"content": "Hello, how are you?"
}
],
"stream": true
}
```
Notes:
- Use a `gemini-*` model for Gemini (e.g., "gemini-2.5-pro"), a `gpt-*` model for OpenAI (e.g., "gpt-5"), a `claude-*` model for Claude (e.g., "claude-3-5-sonnet-20241022"), or a `qwen-*` model for Qwen (e.g., "qwen3-coder-plus"). The proxy will route to the correct provider automatically.
#### Claude Messages (SSE-compatible)
```
POST http://localhost:8317/v1/messages
```
### Using with OpenAI Libraries
You can use this proxy with any OpenAI-compatible library by setting the base URL to your local server:
#### Python (with OpenAI library)
```python
from openai import OpenAI
client = OpenAI(
api_key="dummy", # Not used but required
base_url="http://localhost:8317/v1"
)
# Gemini example
gemini = client.chat.completions.create(
model="gemini-2.5-pro",
messages=[{"role": "user", "content": "Hello, how are you?"}]
)
# Codex/GPT example
gpt = client.chat.completions.create(
model="gpt-5",
messages=[{"role": "user", "content": "Summarize this project in one sentence."}]
)
# Claude example (using messages endpoint)
import requests
claude_response = requests.post(
"http://localhost:8317/v1/messages",
json={
"model": "claude-3-5-sonnet-20241022",
"messages": [{"role": "user", "content": "Summarize this project in one sentence."}],
"max_tokens": 1000
}
)
print(gemini.choices[0].message.content)
print(gpt.choices[0].message.content)
print(claude_response.json())
```
#### JavaScript/TypeScript
```javascript
import OpenAI from 'openai';
const openai = new OpenAI({
apiKey: 'dummy', // Not used but required
baseURL: 'http://localhost:8317/v1',
});
// Gemini
const gemini = await openai.chat.completions.create({
model: 'gemini-2.5-pro',
messages: [{ role: 'user', content: 'Hello, how are you?' }],
});
// Codex/GPT
const gpt = await openai.chat.completions.create({
model: 'gpt-5',
messages: [{ role: 'user', content: 'Summarize this project in one sentence.' }],
});
// Claude example (using messages endpoint)
const claudeResponse = await fetch('http://localhost:8317/v1/messages', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
model: 'claude-3-5-sonnet-20241022',
messages: [{ role: 'user', content: 'Summarize this project in one sentence.' }],
max_tokens: 1000
})
});
console.log(gemini.choices[0].message.content);
console.log(gpt.choices[0].message.content);
console.log(await claudeResponse.json());
```

```
### OpenAI Compatibility Providers
Configure upstream OpenAI-compatible providers (e.g., OpenRouter) via `openai-compatibility`.
- name: provider identifier used internally
- base-url: provider base URL
- api-keys: optional list of API keys (omit if provider allows unauthenticated requests)
- models: list of mappings from upstream model `name` to local `alias`
Example:
```yaml
openai-compatibility:
- name: "openrouter"
base-url: "https://openrouter.ai/api/v1"
api-keys:
- "sk-or-v1-...b780"
- "sk-or-v1-...b781"
models:
- name: "moonshotai/kimi-k2:free"
alias: "kimi-k2"
```
Usage:
Call OpenAI's endpoint `/v1/chat/completions` with `model` set to the alias (e.g., `kimi-k2`). The proxy routes to the configured provider/model automatically.
Also, you may call Claude's endpoint `/v1/messages`, Gemini's `/v1beta/models/model-name:streamGenerateContent` or `/v1beta/models/model-name:generateContent`.
And you can always use Gemini CLI with `CODE_ASSIST_ENDPOINT` set to `http://127.0.0.1:8317` for these OpenAI-compatible provider's models.
### Authentication Directory
The `auth-dir` parameter specifies where authentication tokens are stored. When you run the login command, the application will create JSON files in this directory containing the authentication tokens for your Google accounts. Multiple accounts can be used for load balancing.
### API Keys
The `api-keys` parameter allows you to define a list of API keys that can be used to authenticate requests to your proxy server. When making requests to the API, you can include one of these keys in the `Authorization` header:
```
Authorization: Bearer your-api-key-1
```
### Official Generative Language API
The `generative-language-api-key` parameter allows you to define a list of API keys that can be used to authenticate requests to the official Generative Language API.
## Hot Reloading
The server watches the config file and the `auth-dir` for changes and reloads clients and settings automatically. You can add or remove Gemini/OpenAI token JSON files while the server is running; no restart is required.
## Gemini CLI with multiple account load balancing
Start CLI Proxy API server, and then set the `CODE_ASSIST_ENDPOINT` environment variable to the URL of the CLI Proxy API server.
```bash
export CODE_ASSIST_ENDPOINT="http://127.0.0.1:8317"
```
The server will relay the `loadCodeAssist`, `onboardUser`, and `countTokens` requests. And automatically load balance the text generation requests between the multiple accounts.
> [!NOTE]
> This feature only allows local access because there is currently no way to authenticate the requests.
> 127.0.0.1 is hardcoded for load balancing.
## Claude Code with multiple account load balancing
Start CLI Proxy API server, and then set the `ANTHROPIC_BASE_URL`, `ANTHROPIC_AUTH_TOKEN`, `ANTHROPIC_MODEL`, `ANTHROPIC_SMALL_FAST_MODEL` environment variables.

export ANTHROPIC_AUTH_TOKEN=sk-dummy
export ANTHROPIC_MODEL=qwen3-coder-plus
export ANTHROPIC_SMALL_FAST_MODEL=qwen3-coder-flash
```
## Codex with multiple account load balancing
Start CLI Proxy API server, and then edit the `~/.codex/config.toml` and `~/.codex/auth.json` files.
config.toml:
```toml
model_provider = "cliproxyapi"
model = "gpt-5-codex" # Or gpt-5, you can also use any of the models that we support.
model_reasoning_effort = "high"
[model_providers.cliproxyapi]
name = "cliproxyapi"
base_url = "http://127.0.0.1:8317/v1"
wire_api = "responses"
```
auth.json:
```json
{
"OPENAI_API_KEY": "sk-dummy"
}
```
## Run with Docker
Run the following command to login (Gemini OAuth on port 8085):
```bash
docker run --rm -p 8085:8085 -v /path/to/your/config.yaml:/CLIProxyAPI/config.yaml -v /path/to/your/auth-dir:/root/.cli-proxy-api eceasy/cli-proxy-api:latest /CLIProxyAPI/CLIProxyAPI --login
```
Run the following command to login (Gemini Web Cookies):

```
Run the following command to start the server:
```bash
docker run --rm -p 8317:8317 -v /path/to/your/config.yaml:/CLIProxyAPI/config.yaml -v /path/to/your/auth-dir:/root/.cli-proxy-api eceasy/cli-proxy-api:latest
```
## Run with Docker Compose
1. Clone the repository and navigate into the directory:
```bash
git clone https://github.com/luispater/CLIProxyAPI.git
cd CLIProxyAPI
```
2. Prepare the configuration file:
Create a `config.yaml` file by copying the example and customize it to your needs.
```bash
cp config.example.yaml config.yaml
```
*(Note for Windows users: You can use `copy config.example.yaml config.yaml` in CMD or PowerShell.)*
3. Start the service:
- **For most users (recommended):**
Run the following command to start the service using the pre-built image from Docker Hub. The service will run in the background.
```bash
docker compose up -d
```
- **For advanced users:**
If you have modified the source code and need to build a new image, use the interactive helper scripts:
- For Windows (PowerShell):
```powershell
.\docker-build.ps1
```
- For Linux/macOS:
```bash
bash docker-build.sh
```
The script will prompt you to choose how to run the application:
- **Option 1: Run using Pre-built Image (Recommended)**: Pulls the latest official image from the registry and starts the container. This is the easiest way to get started.
- **Option 2: Build from Source and Run (For Developers)**: Builds the image from the local source code, tags it as `cli-proxy-api:local`, and then starts the container. This is useful if you are making changes to the source code.
4. To authenticate with providers, run the login command inside the container:
- **Gemini**:
```bash
docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI -no-browser --login
```
- **Gemini Web**:
```bash
docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI --gemini-web-auth
```
- **OpenAI (Codex)**:
```bash
docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI -no-browser --codex-login
```
- **Claude**:
```bash
docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI -no-browser --claude-login
```
- **Qwen**:
```bash
docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI -no-browser --qwen-login
```
5. To view the server logs:
```bash
docker compose logs -f
```
6. To stop the application:
```bash
docker compose down
```
