PrimeRouter × Claude Code
Install Claude Code in one clickwired to PrimeRouter
Download an installer with your API key already embedded and double-click it: it installs Claude Code, sets ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN, and backs up your shell profile before appending. Then open a new terminal and run claude. Pay as you go, balance never expires.

The installer is generated for your account and contains one API key. Do not share it.
KEY
Your API key is embedded — nothing to paste
BACKUP
Your shell profile is backed up before one PrimeRouter block is appended
PROTOCOL
A byte-identical Anthropic endpoint — Claude Code just works
QUIET
Telemetry, error reporting and other non-essential traffic switched off
HOW IT WORKS
Three steps
Download and run the installer
You get PrimeRouter-ClaudeCode-Installer.zip. Unzip it and double-click PrimeRouter-ClaudeCode-Installer.command. If macOS blocks the first launch, right-click the file → Open.
You get PrimeRouter-ClaudeCode-Installer.bat. Double-click it and follow the prompts in the window.
You get PrimeRouter-ClaudeCode-Installer.sh. In a terminal run: bash ~/Downloads/PrimeRouter-ClaudeCode-Installer.sh.
Start Claude Code
Open a new terminal (so the new environment variables load) and run claude.
ONE-LINE INSTALL
Already have an API key? One line
No web login needed: the script asks for your API key interactively and never writes it into the command or your shell history.
curl -fsSL https://primerouter.ai/install/claude-code.sh | bash
irm https://primerouter.ai/install/claude-code.ps1 | iex
curl -fsSL https://primerouter.ai/install/claude-code.sh | bash
What it does: checks Node v22+ → installs @anthropic-ai/claude-code globally with npm if missing (asks first) → asks for your API key → backs up your shell profile, then appends ANTHROPIC_BASE_URL, ANTHROPIC_AUTH_TOKEN and CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1.

Most likely a leftover
ANTHROPIC_API_KEY in your terminal: Claude Code prefers it and bypasses PrimeRouter. Run unset ANTHROPIC_API_KEY (Windows: Remove-Item Env:ANTHROPIC_API_KEY), then open a new terminal. Read the guide →The script writes the variables into your shell profile (macOS / Linux) or user-level environment variables (Windows); only a new terminal reads them. Read the guide →
It is generated for you only and contains one key from your account — do not forward it. If it leaks, delete or recreate that key on the API keys page; your other keys are unaffected. API keys page →
Use the Codex CLI install page or the Codex Desktop install page; the same key works for both. Codex CLI install page →
