Claude Max Api Proxy

Claude Max API Proxy

Actively maintained fork of [atalovesyou/claude-max-api-proxy](https://github.com/atalovesyou/claude-max-api-proxy) with OpenClaw integration, improved streaming, and expanded model support.

**Use your existing Claude Code subscription (Pro, Max, or Team) with any OpenAI-compatible client — no separate API costs!**

This proxy wraps the Claude Code CLI as a subprocess and exposes an OpenAI-compatible HTTP API, allowing tools like OpenClaw, Continue.dev, or any OpenAI-compatible client to use your Claude subscription instead of paying per-API-call. It works with any subscription tier that Claude Code itself supports — Pro, Max, or Team — not just Max.

Why This Exists

Approach	Cost	Limitation
Claude API	~$15/M input, ~$75/M output tokens	Pay per use
Claude subscription (Pro/Max/Team)	Flat monthly fee	OAuth blocked for third-party API use
This Proxy	$0 extra (uses your existing subscription)	Routes through CLI

Anthropic blocks OAuth tokens from being used directly with third-party API clients. However, the Claude Code CLI *can* use OAuth tokens from any subscription tier. This proxy bridges that gap by wrapping the CLI and exposing a standard API.
