Install and configure CC-Switch for D1V PAI

Complete the Dashboard credential steps first. You need:

• D1V_PAI_BASE_URL, normally https://pai.d1v.ai/v1
• D1V_PAI_API_KEY, scoped to one project environment
• A model ID returned by GET /models

Use CC Switch 3.17.0 or newer for OpenAI Responses routing. Never choose a preset for another API provider: add a Custom provider so the endpoint remains D1V PAI.

Download the current release from CC-Switch Releases. On macOS:

brew tap farion1231/ccswitch
brew install --cask cc-switch

Initialize each target CLI once before CC-Switch manages it: codex --help, claude --help, or the equivalent command for your client.

1. 1
   Select the target application in the top app switcher.
2. 2
   Click +, keep the application-specific provider tab, then select Custom.
3. 3
   Name it D1V PAI and paste the project key only into the API Key field.
4. 4
   Use the protocol values from the focused client guide. Codex uses Responses; Claude Code can use native Anthropic Messages directly, with local routing reserved for optional protocol conversion.
5. 5
   Save and enable the provider, then restart the target application or terminal process.

   

Claude Code puts the service root in ANTHROPIC_BASE_URL and requests /v1/messages itself. Claude Desktop uses a different takeover flow; follow its focused guide.
