How can one API key configure Claude Code, Codex, and Gemini CLI?
Create an I Code Easy API key in the dashboard, then enter that same key in the documented Claude Code, Codex, and Gemini CLI setups. Each client still needs its own protocol-specific configuration.
Configure each client
Follow Claude Code, Codex, and Gemini CLI one at a time; do not copy one client configuration into another.
Check compatibility first
Use the model capabilities guide to confirm that your selected client and model work together.
Continue setup
Start with environment setup if your terminal or credentials are not ready.
