Hello,
My Google Cloud account is currently at the first-tier level and using the US$300 free trial credits. I also have a valid payment method enabled. Everything had been working normally and Gemini 3 api had been available until December 4th.
Since then, every time I call the Gemini 3 API, I receive the following error:
403 The caller does not have permission
However, Gemini 2.5 Pro still works normally, and other APIs that do not use free trial credits also work without any issues. Additionally, when I test Gemini 3 with another account that is not using the free trial credits, it performs normally.
So, my question is:
Is Gemini 3 currently unavailable for accounts that are using free trial credits?
Or is there any new restriction or requirement I should be aware of?

same issue here! Everything in my project was working great last night, no issues. 3-pro-preview working great.
Woke up this morning to repeated errors:
>[GoogleGenerativeAI Error]: Error fetching from https://generativelanguage.googleapis.com/v1beta/models/gemini-3-pro-preview:generateContent: [403 Forbidden] The caller does not have permission"
JSON error in that link says “Method doesn’t allow unregistered callers (callers without established identity). Please use API Key or other form of API consumer identity to call this API.”
??
2.5-pro, 2.5-pro-flash queries work with no issues. I’m on Tier 1 with credit card attached and more than enough credits… I don’t see any place to modify my API access as recommended online..
Is there somewhere they announced if there’s any major outage or changes to the API…
UPDATE: Just started working for me. I don’t think I did anything must have been an issue on their end.
Seems 3 Pro API just starts working.
