Claude Code can use AI Gateway through the Anthropic-compatible API endpoint. Configure the base URL and API key before starting Claude Code.

<Note>
  Create or copy your API key from the console before configuring Claude Code.
</Note>

## Configure Environment Variables

```bash theme={null}
export ANTHROPIC_BASE_URL=https://llm.gpuhub.com/api/v1/anthropic
export ANTHROPIC_AUTH_TOKEN=$API_KEY
```

If you do not specify a model, Claude Code uses the default model configured by the gateway. You can also route Claude Code model aliases to a specific model.

```bash theme={null}
export ANTHROPIC_DEFAULT_HAIKU_MODEL=GLM-5
export ANTHROPIC_DEFAULT_SONNET_MODEL=GLM-5
export ANTHROPIC_DEFAULT_OPUS_MODEL=GLM-5
```

## Start Claude Code

After the environment variables are set, start Claude Code from your project directory.

```bash theme={null}
claude
```
