I tried to use Gemini for one of my projects a month ago. Immediately after signing up and paying for credits, I got an email saying, “Action required: your billing account {redacted} is past due or has invalid payment information.” I have no idea why it says this. My credit card on file works. My balance updated with a new amount from that card. 11 days later, my account was terminated. I still don’t understand what went wrong or how to fix it.
I do pay for OpenAI, Anthropic, and ElevenLabs keys.
Have you tried using the free tier in https://aistudio.google.com/api-keys? Sorry for your billing issues - these can be super annoying to resolve
