Welcome to CLI Proxy API

CLI Proxy API is a powerful proxy server that bridges the gap between CLI-based AI models and standard AI API interfaces. It provides OpenAI, Gemini, Claude, and Codex compatible endpoints, allowing you to use your existing CLI subscriptions with any tool or library designed for these APIs.

Quick Start

​
Key Features

Multi-Provider OAuth

Authenticate with Gemini, Claude, OpenAI Codex, Qwen, iFlow, and Antigravity using OAuth flows

Load Balancing

Distribute requests across multiple accounts with round-robin or fill-first strategies

Model Aliasing

Create custom model names and map unavailable models to alternatives

Streaming Support

Full support for streaming and non-streaming responses with function calling

Management API

Runtime configuration, quota monitoring, and log access via REST endpoints

Go SDK

Reusable library for embedding the proxy in your own applications

​
Use Cases

​
CLI Subscriptions with Any Client

Use your Gemini CLI, Claude Code, or OpenAI Codex subscriptions with tools like Cursor, Cline, Continue, or any OpenAI-compatible client. 
# Start the proxy
./cliproxyapi

# Use with any OpenAI-compatible client
curl http://localhost:8317/v1/chat/completions \
  -H "Authorization: Bearer your-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gemini-2.5-pro",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

​
Multi-Account Management

Automatically distribute load across multiple accounts to maximize throughput and avoid rate limits. 
# config.yaml - Round-robin across three Gemini accounts
routing:
  strategy: "round-robin"

# Authentication files managed in ~/.cli-proxy-api/
# - gemini_account1.json
# - gemini_account2.json  
# - gemini_account3.json

​
Custom Model Routing

Map model names to different providers or create aliases for your workflow. 
# Route unavailable models to alternatives
ampcode:
  model-mappings:
    - from: "claude-opus-4-5-20251101"
      to: "gemini-2.5-pro"
    - from: "gpt-5"
      to: "claude-sonnet-4"

​
Architecture

CLI Proxy API acts as a translation layer between standard AI API formats (OpenAI, Claude, Gemini) and CLI-based authentication: 
┌─────────────────┐
│  Your Client    │  (Cursor, Cline, custom app)
└────────┬────────┘
         │ OpenAI-compatible API
         ▼
┌─────────────────┐
│ CLI Proxy API   │  Translation & Routing
└────────┬────────┘
         │
    ┌────┴────┬────────┬────────┐
    ▼         ▼        ▼        ▼
  Gemini   Claude   Codex    Qwen
   (CLI)   (OAuth)  (OAuth)  (OAuth)
The proxy handles:
  • Authentication: OAuth flows, token refresh, multi-account management
  • Translation: Request/response format conversion between API standards
  • Routing: Load balancing, model aliasing, automatic failover
  • Management: Configuration hot-reload, quota tracking, logging

​
