IMPORTANT

Please make sure to replace sk-xxx with the Token provided by New API. You can get the API Key from the New API Console.

Direct Launch and Use

After configuring the environment variables, use the terminal to open the project directory you want to work with, then run the following command to start Claude Code:

# Enter the project directory
cd my-project

# Directly start Claude Code
claude

TIP

You can add environment variable configuration to your shell configuration file to avoid manually setting it each time:

export ANTHROPIC_BASE_URL=https://model.imkk.us/
export ANTHROPIC_AUTH_TOKEN=sk-xxx
export ANTHROPIC_API_KEY=sk-xxx

::: tab Windows PowerShell

# Add to PowerShell profile ($PROFILE)
$env:ANTHROPIC_BASE_URL="https://model.imkk.us/"
$env:ANTHROPIC_AUTH_TOKEN="sk-xxx"
$env:ANTHROPIC_API_KEY="sk-xxx"

:::

::: tab Windows CMD

# Add to batch file or system environment variables
set ANTHROPIC_BASE_URL=https://model.imkk.us/
set ANTHROPIC_AUTH_TOKEN=sk-xxx
