Quickstart

1. Join the waitlist to request an invitation, or sign in if you already have an account. Use your invitation link to register, then confirm your email.
2. Open API Keys and create a CyberRouter key for your application. Copy it when it is shown.
3. Connect your provider key using the BYOK guide. Your provider must have the required API balance and model access.
4. Check your available CyberRouter credits on the Credits page. These pay the CyberRouter service fee.

Examples use DeepSeek Flash. Connect a DeepSeek provider key first, or replace the model ID with a supported model from your catalog. Set CYBERROUTER_API_KEY in your application environment to the key you created in CyberRouter.
