# CyberRouter

> CyberRouter is a bring-your-own-key (BYOK) AI gateway that connects supported model providers through one API and adds security reference context for code review, incident response, and other security work.

Applications authenticate with a CyberRouter account API key. Connected provider keys authorize upstream model requests. Provider usage charges and CyberRouter credits and fees are separate; see the current pricing and billing documentation.

The model catalog describes supported models and provider connections. Actual availability depends on the user's connected provider accounts and their model permissions. The linked pages contain the current documentation, pricing, and policies.
