Claude Code

Anthropic's terminal-native coding agent, running on Omnizen models.

What you get

Claude Code talks to the Anthropic Messages API. Point it at Omnizen and every request runs through our smart router — Claude when you need it, cheaper frontier models when you don't, no code changes either way.

Install

If you don't already have it:

bash

npm install -g @anthropic-ai/claude-code

Configure

Two environment variables. Add them to your shell profile:

~/.zshrc or ~/.bashrcbash

export ANTHROPIC_BASE_URL="https://api.omnizen.ai"
export ANTHROPIC_AUTH_TOKEN="sk-omni-…"

Or, if you'd rather keep it project-local, drop them into a per-project .envrc or ~/.claude/settings.json:

~/.claude/settings.jsonjson

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.omnizen.ai",
    "ANTHROPIC_AUTH_TOKEN": "sk-omni-…"
  }
}

Run it

bash

claude

That's it. claude now routes through Omnizen. The router picks the model — pass --model to override (any model name we publish on /models).

Tips

Rotate your key any time from the dashboard — old keys keep working until you delete them.
Per-project settings override your shell profile, so one repo can route through a scoped key with a spend cap while the rest of your machine uses your default.
Plan-mode prompts still work — Claude Code's tool surface doesn't change, just the backend.
