For Claude, the API URL is different from Codex and does not need the /v1 suffix.
Use the claude_code or official Claude relay group when possible.

Download the correct CCSwitch version for your OS.

Open CCSwitch, choose Codex, and click the + button in the top-right corner.

Set the provider name to ai-one and leave the website field empty.

Open https://ai-one.vip and copy your token from token management.

Paste the copied key into the API Key field.

Set the API request URL to https://ai-one.vip without the /v1 suffix.

Set the auth field to ANTHROPIC_API_KEY, leave model mapping empty, and click Add.

Use the shown button to open a Claude terminal quickly.

Choose Yes in the first prompt.

Choose Yes again in the second prompt.

After initialization, Claude is ready for chat.

Run /model to choose another model.

Setup is complete and Claude CLI can now call models through the configured endpoint.
