Can I have keys from two providers at the same time, for example to split usage? No — only one own key active at any time (section 3). To switch providers, use “Change key” and confirm the replacement.
Do I get to see my full key again after saving it? No, never — only the last characters, as a reference (“Ends in ‹hint›”). If you lose it or forget it, you’ll need to ask your provider for a new one and replace it here.
What happens to my conversations while my key is “Suspicious” and I DON’T have fallback on? That turn fails with an honest notice instead of generating a cost you wouldn’t be able to see reflected on your provider’s bill (section 6) — turn it on if you’d rather the platform answer with its own key while you resolve the problem.
Does automatic fallback mix my usage with my own key’s in the breakdown? No — fallback has its own row (“Fallback”) in the breakdown by source, separate from “Your own key” (section 5).
Can I use an endpoint on my own internal network or a private IP as a “custom endpoint”?
No — only public https:// addresses with a full domain name are accepted; an internal, local, or private IP address is rejected when saving, with no exceptions (section 2).
Can I choose any provider from the list? Only the ones the platform has available at any given time — if you picked one that isn’t, the form itself tells you when you try to save, before saving anything.
What happens to an agent that had a model from another provider pinned? It becomes “unavailable” with a reason until you change its model (section 4) — it’s never secretly served with a different provider than the one pinned.
