Claude Code by CCS

Configure Claude Code with UnifyLLM through CC Switch.

Integration Overview

This page explains how to connect Claude Code to UnifyLLM through CC Switch. Add UnifyLLM under Unified Providers, choose the NewAPI preset, enable Claude Code, use the root endpoint, and select native Anthropic Messages.

Install Claude Code First

Install the client from the Claude Code official documentation or release page before configuring CC Switch. The command below is a common npm/pipx method; follow the official page if the current release uses a different command.

  • macOS / Linux: use Terminal, iTerm2, or bash/zsh; reopen the shell after installation so PATH changes take effect.
  • Windows: use Windows Terminal or PowerShell. Use npm for Node-based tools and pipx for Python tools; avoid mixing Python environments.
  • Run the tool's --version or official launch command before adding an API provider, so you know the client itself works.
bash
1# macOS / Linux / Windows Terminal2npm install -g @anthropic-ai/claude-code3 4# verify the installation5claude --version

Before You Start

  • API Base URL: https://api.unifyllm.top
  • An active UnifyLLM API key
  • A currently available model ID, for example claude-sonnet-4-6. Models, groups, and prices can change; use the live pricing page and console model list as the source of truth.

Configure It in CC Switch

  1. 1

    Install and open CC Switch

    Open provider management and select Claude Code in the application switcher.

  2. 2

    Open Unified Providers

    Click + and add UnifyLLM under Unified Providers, not under an application-specific provider list.

  3. 3

    Choose the NewAPI preset

    Set the preset type to NewAPI and name the provider UnifyLLM.

  4. 4

    Choose the format and endpoint

    Select Anthropic Messages (native format), use https://api.unifyllm.top, and paste your API key. Never put the key in screenshots, repositories, or public logs.

  5. 5

    Add and select a model

    Add claude-sonnet-4-6 or choose the exact ID from Get Models. If the list is empty, check the endpoint, key, and whether /v1 was entered twice.

  6. 6

    Enable the provider

    Enable the card and restart the tool as required by Claude Code. Add UnifyLLM under Unified Providers, choose the NewAPI preset, enable Claude Code, use the root endpoint, and select native Anthropic Messages.

Manual Configuration Reference

If you are not using CC Switch, the following is a reference for the common configuration format of this tool. Field names can change between releases, so prefer the tool's own documentation when it differs.

bash
1export ANTHROPIC_BASE_URL="https://api.unifyllm.top"2export ANTHROPIC_API_KEY="<YOUR_API_KEY>"3export ANTHROPIC_MODEL="claude-sonnet-4-6"

Test and Troubleshoot

Restart Claude Code after switching providers, then ask it to inspect a small file. If the request succeeds, confirm the model and usage in the console.

API references: Chat Completions, Responses, Messages, and Generate Content.

  • Start with a short request before running a large workload.
  • Match the model ID exactly with the pricing page and console, including any group prefix.
  • Review console usage logs for delivery, the actual model, token usage, and errors.
  • If the tool appends /v1 automatically and you entered /v1 manually, remove the duplicate path.

Official CC Switch References

This guide references the official CC Switch introduction, Add Provider, and Edit Provider. Field names and paths may change after a CC Switch update; use its latest documentation and application UI as the final reference.

Security Reminder

An API key is an account credential. Use a dedicated key, limit where it is stored, and disable/recreate it immediately if it leaks. Never place it in browser code, a public repository, screenshots, or third-party sync services.
