[FIX] "Usage Limit Exceeded" on Mimo CLI / Unlocking OpenCode Free Models with Zen-Proxy

💡 Fix for "Usage Limit Exceeded" Error on Alternative Coding Agents

If you are getting a "Usage Limit Exceeded" error on the Mimo CLI after only making one or two requests, the issue is that OpenCode has restricted their free models to only work directly within the official OpenCode TUI. They do this by checking the User-Agent (UA) header in your requests.

To fix this, I created an open-source proxy called Zen-Proxy.

🛠️ How it works

The proxy acts as a middleman. When you send a request from an external coding agent, Zen-Proxy intercepts it, changes your default User-Agent header to the official OpenCode UA, and passes it through. This unlocks the free models for use in any coding agent.

🚀 Key Features

• Simple Setup: Route your OpenCode base URL to the proxy URL, and you are good to go.
• Easy Installation: Installs quickly using a single curl command.
• Dashboard: Includes a clean, beautiful web dashboard to monitor and manage your requests.
