MiMo Code API Key Setup — Terminal Coding Agent Guide

MiMo Code is Xiaomi’s terminal coding agent. APIMaster.ai exposes an OpenAI-compatible API — add it in MiMo Code with the /connect wizard (custom provider).

Get an API Key first. Paste the key only inside MiMo Code; never share it in chat or screenshots.
