MiniMax moved their Anthropic-compatible API from api.minimax.io to api.minimaxi.chat. The old endpoint returns 404; the new one returns 200. Key is unchanged and still valid. Native api.minimax.io endpoints (e.g. subscription check) are unaffected. Claude-Session: https://claude.ai/code/session_01XtWRazqRbMnMRa4iV3zbVx
