My prepay credit balance ran out (spend for Sept 1–8 was ~$149 USD), and AI Studio showed the banner “A credit balance above $0 is required to resume service.” All Gemini API calls were failing with `permission denied` at that point, which made sense given the $0 balance.
I added NT$1,000 in new credit and turned on auto-reload. The balance now shows NT$2,000 and the low-balance warning is gone. However, API calls are still failing with the same error:
Failed to generate content: permission denied. Please try again.
This happens in the AI Studio Playground with every model I’ve tried, not just one — I tested both gemini-3.5-flash and gemini-3.5-flash-lite and got the identical error on both. The Gemini API is shown as “Enabled” in Cloud Console for this project, so it doesn’t appear to be a disabled-API issue. The underlying error is a gRPC PERMISSION_DENIED (status code 7) from the GenerateContent RPC.
This looks like it may be a Trust & Safety hold placed on the project when the balance hit $0, which didn’t automatically clear when I topped up the balance. Could someone take a look and manually review/lift the restriction on this project? Happy to provide any additional details needed.
