Codex

Codex can use an OpenAI-compatible gateway. Configure the OpenAI base URL as UURoute and use your UURoute API key.

Environment Variables

export UUROUTE_API_KEY="<UUROUTE_API_KEY>"
export OPENAI_BASE_URL="https://api.uuroute.ai/"
export OPENAI_API_KEY="$UUROUTE_API_KEY"

Use an OpenAI-compatible model available through UURoute:

codex --model gpt-5-codex

If you want Codex to proceed without additional prompts, use:

codex --model gpt-5-codex --full-auto

For a one-shot prompt:

codex --model gpt-5-codex "Review this repository and summarize the main risks."

Add the variables to your shell profile:

export UUROUTE_API_KEY="<UUROUTE_API_KEY>"
export OPENAI_BASE_URL="https://api.uuroute.ai/"
export OPENAI_API_KEY="$UUROUTE_API_KEY"

Restart your shell after updating the profile.
