SecondRail key setup — visible to all users
- Get OpenRouter key — create a key, add credits if you need paid models, then return here.
- Get Anthropic key — create a key in Settings > API keys, add billing/credits, then return here.
- Return to SecondRail and finish here.
Finish here
After you get a key, switch back to this tab or use a return link below — setup finishes on SecondRail, not on the provider site.
Providers do not auto-redirect back to SecondRail themselves. These buttons open them in a new tab, so SecondRail stays open; the return links above complete the flow on SecondRail.
