Claude Code is Anthropic’s official CLI and connects to Anthropic’s own gateway by default. Two environment variables route it through DimiLinks. The fastest method is CC Switch:
  1. Install CC Switch and sign in.
  2. On the API Keys page in the DimiLinks console, click “Import to CC Switch” for a key restricted to Claude models.
  3. CC Switch automatically adds a provider named Claude with the base URL set to https://api-direct.dimilinks.com/.
  4. Before starting Claude Code, run cc-switch use <provider> to switch to DimiLinks.
See One-click import into CC Switch / Cherry Studio for the deep-link structure.

​
Configure environment variables manually

If you do not use CC Switch, set the environment variables directly: 
export ANTHROPIC_BASE_URL="https://api-direct.dimilinks.com/"
export ANTHROPIC_AUTH_TOKEN="sk-..."
Then start Claude Code: 
claude
Add the variables to your shell configuration (~/.zshrc or ~/.bashrc) to persist them. To maintain multiple configurations for different keys, use a tool such as direnv or mise to inject them by directory.
Claude Code does not read the OpenAI-compatible endpoint. You must use https://api-direct.dimilinks.com/, not dimilinks.com/v1.

Use the /model command after startup to switch models. Model IDs match the List models response.

Troubleshooting

  • 401 Invalid token: The environment variable is not active or the key is incorrect. Run echo $ANTHROPIC_AUTH_TOKEN to check it.
  • 403 model_not_allowed: The key’s model restrictions do not allow the Claude model you selected. Update the key in the console.
  • Requests keep timing out: Start with the minimal curl example under Authentication. If curl succeeds but Claude Code does not, a local proxy or corporate VPN is probably blocking the request.
  • Keep an official Anthropic account available as well: Maintain multiple providers in CC Switch and run cc-switch use anthropic before startup to switch back.
