# Claude Code

> Run Claude Code on a DigitSpace key or DevPass with any model, including auto, by setting two environment variables.

Claude Code speaks Anthropic's Messages API, which DigitSpace serves for every model. Point it at DigitSpace with environment variables.

Shell:

```bash
export ANTHROPIC_BASE_URL=https://api.digitspace.ai
export ANTHROPIC_AUTH_TOKEN=your-digitspace-key
export ANTHROPIC_MODEL=auto
export ANTHROPIC_SMALL_FAST_MODEL=auto:economy
claude
```

settings.json:

```json
{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.digitspace.ai",
    "ANTHROPIC_AUTH_TOKEN": "your-digitspace-key",
    "ANTHROPIC_MODEL": "auto",
    "ANTHROPIC_SMALL_FAST_MODEL": "auto:economy"
  }
}
```

`ANTHROPIC_BASE_URL` has no `/v1`; Claude Code adds the path. Put the settings in `~/.claude/settings.json` to apply them to every session, or in a project's `.claude/settings.json` for one project. Newer Claude Code versions name the small model `ANTHROPIC_DEFAULT_HAIKU_MODEL`; set it the same way.

## Choosing models

- `auto` lets DigitSpace pick a model for each request. Claude Code sends tools with nearly every request, so `auto` uses standard models or better.
- Any model ID works, Claude or not: `ANTHROPIC_MODEL=claude-sonnet-5-5`, or `gpt-6-luna`. Non-Claude models get the request translated; see [Anthropic Messages](/docs/api/messages).
- In a session, `/model` switches model.

## Things to know

- Claude Code's built-in **web search** is an Anthropic server tool. It's removed on credits and DevPass, and works only on your own Anthropic key.
- A [DevPass](/docs/devpass) key works here unchanged. Watch its meters with `GET /v1/key` (see [Limits and meters](/docs/devpass/limits)).
- Claude Code's sessions, cost and requests appear on the dashboard's **Agents** page.
