Codex Installation

When this page is useful

Use this page when you are about to connect a local terminal tool, script environment, or compatible client to the Codebyby relay and want the smallest possible setup path first.

Confirm these prerequisites first

• You already have the current relay base URL
• You already have a valid API key
• Your local network can reach the relay
• You know whether you are setting up a terminal tool, IDE plugin, or script runtime

Recommended preparation order

1. Confirm that your client supports a custom base URL.
2. Decide where the environment variables or config file will live.
3. Fill in the relay base URL and API key.
4. Send one minimal request as a connectivity check.
5. Only after validation, continue with heavier tooling or automation.

Installation principles

• Get the smallest working path first, then add plugins or automation.
• Prefer environment variables instead of hardcoding secrets.
• If multiple tools share one machine, keep one clear source of truth for the relay address.

First thing to do after setup

Do not send production traffic immediately. First verify that:

• the address is correct
• the key is valid
• the model name works
• the response is normal
