Use Your Own API Key from Any Provider

The problem

You already have API keys and billing set up with providers like GLM, DeepSeek, or MiniMax. You want to use those accounts through Claude Code without switching tools or rewriting configs.

The fix

Use claude-multi's provider templates to wire your existing key into an isolated Claude Code instance. One setup, one command, done.

Bring what you already have

If you are paying for API access to GLM, DeepSeek, MiniMax, or any OpenAI-compatible provider, you should not have to learn a new tool to use it. claude-multi takes the key you already have and wraps it in the Claude Code interface you already know.

The setup

claude-multi

Pick Add new instance. The wizard walks you through:

Name your instance — something short like glm, deepseek, minimax
Pick a template — claude-multi sets the base URL, model name, and required env vars
Paste your key — it is masked while you type and stored in the instance’s own settings.json
Confirm paths — config at ~/.claude-<name>/, binary at ~/.local/bin/claude-<name>
Done — run claude-glm (or whatever you named it)

claude-glm "explain this concurrency bug"

That is a full Claude Code session, using your GLM key, with its own config directory.

Available templates

Template	Provider	What it sets
`glm`	GLM / Z.ai	`ANTHROPIC_BASE_URL`, `ANTHROPIC_MODEL`
`minimax`	MiniMax	Endpoint and model for MiniMax
`deepseek`	DeepSeek	Endpoint and model for DeepSeek
`mimo`	Xiaomi MiMo	Xiaomi’s coding endpoint
`kimi`	Moonshot Kimi	Moonshot’s API
`qwen`	Alibaba Qwen	Alibaba’s international endpoint

What happens with your key

The key gets written to ~/.claude-<name>/settings.json as part of the ANTHROPIC_AUTH_TOKEN env var. claude-multi does not send it anywhere. It stays on your machine, in a file that only you (and the Claude Code process) can read.

Multiple keys, multiple instances

You are not limited to one. Create an instance for each provider you have access to:

claude-glm      # your GLM account
claude-deepseek # your DeepSeek account
claude-minimax  # your MiniMax account

All of them run the same Claude Code binary. Same interface, same skills, different brain behind the curtain.
