Add your provider keys
Keys are encrypted on SecondRail with the vault key and stored encrypted. They are never logged or shown back to you. Get them first from the key setup page.
Dogfood only: this page identifies you by customer ID. Before any public launch, key setup must require an authenticated customer credential.
Primary rail
Calls try the primary rail first, then fall over to the other one. If your Anthropic account is empty, make OpenRouter primary.
