cu/claude-4.6-opus-maxHow Cursor IDE billing works with kRouter
Cursor IDE connects with your existing subscription — kRouter signs in with OAuth and reuses the plan you already pay for, so there is no per-token bill. kRouter authenticates it via oauth. 14 models are routable as cu/<model>.
Through kRouter, Cursor IDE serves chat and code completion. Requests reach it through the same local OpenAI-compatible endpoint as every other provider, so switching to or from Cursor IDE is a one-line model change in your client rather than a rewrite.

Cursor IDE FAQ
Is Cursor IDE free through kRouter?
Cursor IDE does not bill per token here — kRouter uses your existing subscription via OAuth, so the only cost is whatever you already pay Cursor IDE directly. kRouter itself is MIT-licensed and free.
How do I use Cursor IDE with Claude Code or Cursor?
Connect Cursor IDE in the kRouter dashboard, then point your tool at kRouter's local endpoint (http://localhost:20128/v1) with a kRouter API key. Any OpenAI-compatible client works, and models are addressed as cu/<model>.
Which Cursor IDE models can kRouter route to?
14 models, including Auto (Server Picks), Claude 4.5 Opus High Thinking, Claude 4.5 Opus High. Every one is addressed as cu/<model> from any client.
What happens when Cursor IDE is rate limited?
kRouter detects the limit, parks that account until its real reset time, and fails over to your next connected account or provider — so the request still completes instead of erroring.
