The CLIProxyAPI project wraps multiple AI code generation tools (Antigravity, ChatGPT Codex, Claude Code, Grok Build, Muse Code, Davin) into a unified OpenAI/Gemini/Claude/Codex compatible API service. This abstraction enables developers to access the free Gemini, GPT, Grok, and Claude model series through a single API interface. The repository provides a convenient, centralized endpoint for integrating diverse language model capabilities without managing separate provider credentials.
