Cursor Customer API Keys

I been using cursor recently and loving the features it provides but I think this is misleading and needs to be addressed.

‘Anthropic API Key
You can put in your Anthropic key to use Claude at cost. When enabled, this key will be used for all models beginning with “claude-”.’ - Cursor Settings page

even with my key put in expecting it to allow me to continue using cursor it still doesn’t let me

A You’ve reached your trial request limit
Please upgrade to Pro to continue.

even after selecting claude models in the dropdown menu.

Previously I had my key switched on and was running into rate limits when using composer and my settings page was not using my credits for cursor pro trial.

After hitting the limit now it wont let me use the api key

Hey, in Composer, your API keys don’t work because Composer uses our specially configured models. To use it, you need a Pro subscription.

I’ve been reading this but why is it when I use my APIkey with cursor I get my API Key limits in composer and its actively using while looking in anthropic, Like when turned on IT IS using my key.

Because when the API key is enabled, the request still goes through but doesn’t receive a response, and it is immediately blocked by Cursor when it detects that it’s being used in Composer.
