CLI Proxy API

English | 中文 | 日本語

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.

Sponsor

This project is sponsored by Z.ai, supporting us with their GLM CODING PLAN.

GLM CODING PLAN is a subscription service designed for AI coding, starting at just $10/month. It provides access to their flagship GLM-4.7 & （GLM-5 Only Available for Pro Users）model across 10+ popular AI coding tools (Claude Code, Cline, Roo Code, etc.), offering developers top-tier, fast, and stable coding experiences.

Amp CLI Support

CLIProxyAPI includes integrated support for Amp CLI and Amp IDE extensions, enabling you to use your Google/ChatGPT/Claude OAuth subscriptions with Amp's coding tools:

• Provider route aliases for Amp's API patterns (/api/provider/{provider}/v1...)
• Management proxy for OAuth authentication and account features
• Smart model fallback with automatic routing
• Model mapping to route unavailable models to alternatives (e.g., claude-opus-4.5 → claude-sonnet-4)
• Security-first design with localhost-only management endpoints

When you need the request/response shape of a specific backend family, use the provider-specific paths instead of the merged /v1/... endpoints:

• Use /api/provider/{provider}/v1/messages for messages-style backends.
• Use /api/provider/{provider}/v1beta/models/... for model-scoped generate endpoints.
• Use /api/provider/{provider}/v1/chat/completions for chat-completions backends.

These routes help you select the protocol surface, but they do not by themselves guarantee a unique inference executor when the same client-visible model name is reused across multiple backends. Inference routing is still resolved from the request model/alias. For strict backend pinning, use unique aliases, prefixes, or otherwise avoid overlapping client-visible model names.
