Openrouter Proxy

OpenRouter Proxy

A zero-dependency proxy that unlocks **free Xiaomi MiMo** on OpenRouter for any client, and fixes **SSE streaming** issues with the VS Code Claude Code extension.

The Problem

**Free MiMo for any tool** — [Xiaomi MiMo](https://openrouter.ai/xiaomi/mimo-v2-pro) is free on OpenRouter, but only when requests come through the **OpenClaw** channel. Without the right headers, you pay or get nothing. This proxy injects them automatically — works with any HTTP client.

**Claude Code SSE fix** — The VS Code Claude Code extension breaks when consuming OpenRouter's SSE stream due to:

• unsupported content type: redacted_thinking errors
• Duplicate or out-of-order events
• Missing content block boundaries

The SSE repair logic specifically targets Claude Code's Anthropic-style event format. Other tools (Continue, Cline, etc.) get the free MiMo access without needing the SSE fix.

**OpenRouter Proxy handles both — transparently, with zero dependencies.**
