Not using my own API key, but do get that error

I am not using my own API key for Anthropic but Cursor does give me the error that I do and does not process my request. What is going wrong here? I get this error with all my Anthropic models suddenly, I did not have this an hour ago. I did run out of the 500 fast request but I enabled usage based pricing. Not sure if that is related but I thought I’d include it here.
