Need clarification with my own API key

Greetings,

I have a Pro Cursor subscription and today my employer offered me a company API key for Anthropic models. It is unclear to me now, how does it work, because I want to keep my subscription and use the auto mode for lighter tasks and for heavier ones the Claude models, but I got a notification after turning on my own API key “With your Cursor Pro subscription, you do not need to use your own Anthropic key”.

So my questions are :

1. if I switch to Claude models after Anthropic API key activation, will Cursor “pull” the quota from my included subscription API limit, or from the API key?

2. Does this limit somehow the usage of Cursor? Because I’ve got some notification, that several functions cannot be billed to an API key, like agent, tab. So I am now confused a bit.

Thank you very much for the answers!

Best regards,
Peter
