Hitting rate limits - all gemini models

I have a script which calls gemini for some insights and planning. I have a free tier currently. The issue is even when i have called the gemini API only 15times all for testing purposes in a span of 60mins, it has started showing me errors that I have hit the rate limit. I opened my dashboard to check the usage and it does not show any usage (I am looking at the right project, double checked it).

What am I missing?
