Agent setup

Codius App can prepare compatible coding agents automatically. You connect one organization API key to the host; the App validates it, stores it outside your projects, and supplies provider settings only to sessions it launches.

1. Create a Codius API key

Subscribe, open API Keys, choose Add API key, and copy the secret while it is visible.

Open API Keys

2. Connect the App

1. Open Codius App.
2. Open Host Settings → Providers → Codius models.
3. Paste the key and select Connect.
4. Keep Use Codius models automatically enabled.
5. Choose the default model shown after validation.

The App never displays the key again. It shows only the last four characters so you can identify which credential is connected.

3. Start a supported agent

Start Claude Code, Codex, OpenCode, GitHub Copilot, or Pi from Codius App. The App applies the provider and default model at launch. No agent configuration file needs to be copied, merged, or overwritten.

What the App changes

• It validates the key against the live model catalog before saving.
• It keeps the credential in the host's protected model-access store.
• It constructs session-scoped provider settings for the selected agent.
• It does not edit the agent's user or project configuration files.
• It does not replace explicit workspace provider choices.

Using the API outside Codius App

For scripts, SDKs, and tools outside the App, use the API quickstart. Those clients manage their own credentials and configuration.

For agent-specific behavior, see Supported providers and the integration guides.
