Claude Code on free models

Two lines of setup. Free models bill $0 per token, with no card required.

Setup

curl -fsSL https://anyrouter.dev/setup.sh | bash
anyr claude --model anyrouter/free

The first run asks you to sign in, creates a key and saves it. Prefer your own setup? Point Claude Code at AnyRouter with two environment variables.

Manual setup

export ANTHROPIC_BASE_URL="https://anyrouter.dev/api"
export ANTHROPIC_API_KEY="sk-ar-your-anyrouter-key"
