Before you start: two values you need

Setting	Value	Where to get it
`ANTHROPIC_BASE_URL`	`https://api.ourtoken.ai`	Copy this value directly
`ANTHROPIC_AUTH_TOKEN`	Your OurToken API Key	Create it on the OurToken API Keys page

Important

ANTHROPIC_BASE_URL should be exactly:
text
https://api.ourtoken.ai
Do not append /v1/messages. Claude Code adds the request path automatically.

Step 1: Install Claude Code

Mac users

Open Terminal, then paste and run:

bash

curl -fsSL https://claude.ai/install.sh | bash

After installation, add Claude Code to your system PATH so the claude command can run:

bash

p="$HOME/.local/bin"; grep -qxF 'export PATH="$HOME/.local/bin:$PATH"' "$HOME/.zshrc" 2>/dev/null || echo 'export PATH="$HOME/.local/bin:$PATH"' >> "$HOME/.zshrc"; export PATH="$p:$PATH"; claude --version

Windows users

Search for PowerShell in the Start menu, open it, then paste and run:

powershell

irm https://claude.ai/install.ps1 | iex

After installation, add Claude Code to your system PATH so the claude command can run:

powershell

$p="$env:USERPROFILE\.local\bin"; $u=[Environment]::GetEnvironmentVariable("Path","User"); if (($u-split";")-notcontains$p){[Environment]::SetEnvironmentVariable("Path",$u.TrimEnd(";")+";"+$p,"User")}; $env:Path+=";$p"; claude --version

Run:

bash

claude --version

If the version number appears, installation is complete.

⚠️ If the claude command does not run, check whether Claude Code has been added to your system PATH.

⚠️ After installation, do not sign in with an Anthropic account. The next step connects Claude Code directly with your OurToken API Key.

Step 2: Configure OurToken credentials

After Claude Code is installed, open the following configuration file. If the file or folder does not exist, create it manually.

Configuration file path

Mac:
text
```
~/.claude/settings.json
```

Windows:

text

C:\Users\<username>\.claude\settings.json

For Windows, replace <username> with your Windows username.

Paste the following into settings.json, then replace your ourtoken api key with your OurToken API Key:

json

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "your ourtoken api key",
    "ANTHROPIC_BASE_URL": "https://api.ourtoken.ai",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-opus-4-8",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL_NAME": "claude-opus-4-8",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-4-8",
    "ANTHROPIC_DEFAULT_OPUS_MODEL_NAME": "claude-opus-4-8",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-6",
    "ANTHROPIC_DEFAULT_SONNET_MODEL_NAME": "claude-sonnet-4-6",
    "ANTHROPIC_MODEL": "claude-sonnet-4-6",
    "ENABLE_TOOL_SEARCH": "true"
  },
  "model": "sonnet",
  "effortLevel": "medium",
  "autoUpdatesChannel": "latest"
}

Note

You can replace the models in the configuration file with other supported models. Check the current model list on the OurToken API Keys page.

Step 3: Verify the configuration

Open Terminal or PowerShell and run this command in any directory:

bash

claude

After entering the Claude Code interface, send a simple message:

text

Hello

If Claude Code replies normally, it is connected to the OurToken API.

You can also sign in to OurToken and check the Dashboard for API call records and cost details.

✅ Claude Code replies normally
✅ API usage appears in the OurToken Dashboard
✅ Your account balance is charged correctly

Once all checks pass, you can start using Claude Code.

Next: use VS Code plugin and Claude Code client

After this setup, you can also use Claude Code directly in the VS Code + Claude Code plugin or in the Claude Code client. They reuse the OurToken credentials already configured on your machine, so you do not need to configure them again.
