Configure MiniMax API

Important: Clear Anthropic Environment Variables Before ConfigurationBefore configuring, ensure you clear the following Anthropic-related environment variables to avoid conflicts with MiniMax API:
  • ANTHROPIC_AUTH_TOKEN
  • ANTHROPIC_BASE_URL
  1. Edit or create the Claude Code configuration file located at ~/.claude/settings.json. In this file, add or update the env field as shown below.
  • The ANTHROPIC_BASE_URL should be set based on your location: for international users, use https://api.minimax.io/anthropic; for users in China, use https://api.minimaxi.com/anthropic.
  • Set <MINIMAX_API_KEY> to the API key obtained from the MiniMax Developer Platform (For users in China, visit MiniMax Developer Platform).
  • Note: Environment variables ANTHROPIC_AUTH_TOKEN and ANTHROPIC_BASE_URL take priority over settings.json configuration.
{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.minimax.io/anthropic",
    "ANTHROPIC_AUTH_TOKEN": "<MINIMAX_API_KEY>",
    "API_TIMEOUT_MS": "3000000",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": 1,
    "ANTHROPIC_MODEL": "MiniMax-M2.1",

    "ANTHROPIC_DEFAULT_OPUS_MODEL": "MiniMax-M2.1",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "MiniMax-M2.1"
  }
}
  1. After completing the configuration, navigate to your working directory and run the claude command in the terminal to start using Claude Code. After startup, select Trust This Folder to allow it to access the files in your folder as shown below:
