Claude API Switch

Manage and switch Claude Code API endpoint profiles — no Claude Code login required, just plug in your API key and go.

⚡ What is this?

Claude Code connects to an AI backend via API. When you use providers like DeepSeek, Alibaba Qwen, or a local proxy, you need to set environment variables (ANTHROPIC_BASE_URL, ANTHROPIC_AUTH_TOKEN, etc.) in your editor's settings.json.

This extension gives you a sidebar UI to manage those configurations as named profiles and switch between them with a single click. No more digging through JSON files by hand.

🚫 No Claude Code account needed. This extension only writes environment variables to settings.json. You bring your own API key from any Anthropic-compatible provider — it works immediately after you fill in the API endpoint and token. No login, no registration, no account required.

🚀 Quick Start — Add Your First Profile (3 Steps)

The simplest operation: add a profile, apply it, done.

Step ① — Open the sidebar

Click the server icon $(server-environment) in the activity bar (left edge of your editor). The "API Profiles" panel slides open.

Step ② — Click + and fill in your key

Click the + button in the sidebar toolbar → Enter a name (e.g. My DeepSeek) → Pick a template (DeepSeek / Aliyun / Anthropic / Local Proxy).

A web form opens with most fields pre-filled. The only thing you need to do is replace ANTHROPIC_AUTH_TOKEN with your actual API key, then click Save.

Step ③ — Apply and test

• Click the ✓ (Apply) inline button on your new profile → writes the config to settings.json
• Click the ▶ (Test) button → verifies the endpoint is reachable and shows latency + model info

That's it. Claude Code is now using your configured API. The whole process takes under 30 seconds.

🖥️ Extension Interface — Where to find everything

The extension is designed so you can figure it out just by looking at the sidebar:

Each profile in the sidebar shows its name, notes preview, and usage count — active profile is marked with a ★ star.
