Frequently asked questions

Does a ChatGPT plan include a Platform API key?

No. Relmio 0.14.0 handles provider OAuth only. Ordinary API-key connections belong directly in n8n or your app. The ChatGPT n8n OAuth bridge remains unofficial, private, and policy-uncertain.

Can I use my SuperGrok subscription?

Yes. The experimental Grok Build adapter uses the official CLI's OAuth and a separate local Relmio bearer. It supports local apps and private n8n companions on the same computer or a VPS. It does not require ChatGPT sign-in, request an xAI API key, or fall back to separately billed API access.

For n8n, SuperGrok requires Use Responses API off. The OpenAI OAuth/Codex recipe uses the switch on in OpenAI Chat Model node version 1.3.

ChatGPT/Codex sign-in tokens expire, but the official Codex client refreshes them automatically during active use before they expire, so active sessions usually continue without another browser login. The official OpenAI authentication documentation does not publish a fixed 10-day lifetime; do not plan around one. This provider credential is separate from Relmio's local capability, which remains valid until you rotate it.

Can I expose local endpoints on my network?

No. Local endpoints bind to 127.0.0.1. Do not port-forward, reverse proxy, or publish a Codex route.

Why does the Chat Adapter reject browser requests?

It rejects every request with an Origin header. Use a trusted local backend or development server. The built-in tester talks to the protected wizard, which makes the server-side adapter request.

Is the built-in tester end-to-end encrypted?

No. It uses an expiring in-memory RSA-OAEP key to reduce accidental credential exposure. It is not encryption at rest or end-to-end encryption, and it cannot protect a compromised browser, extension, or computer.

Can Relmio modify my n8n deployment?

No. The local and VPS routes add a separate sidecar after you approve the plan. They do not edit, exec into, rebuild, restart, stop, or recreate n8n. They never publish port 10531 on the host.

The local n8n AI Assistant tools option creates Relmio-owned Code Sandbox services and optional SearXNG. It publishes no host port and leaves n8n unchanged. The privileged Docker-in-Docker runner is for local testing. Use Daytona for production sandboxing.
