Use Claude Desktop with an API key

1. In Claude Desktop, open Help → Troubleshooting → Enable Developer Mode, and restart when asked.
2. Open Developer → Configure Third-Party Inference.
3. Choose gateway as the provider. Enter https://relay.roamai.cloud:18443 as the Base URL and your key as the API key.
4. Save, then quit and reopen Claude Desktop.

The model picker lists the models your key can use. If an admin limited the key to certain models, only those are listed.

• SSH sessions, cloud environments and Remote Control are not available.
