Constant "quota exceeded" for any project/key on gemini API

Hello,
As you can see in the title, whenever I try to use the gemini API (after not using for 1 day in order to test it), I am met with this message:
google.genai.errors.ClientError: 429 RESOURCE_EXHAUSTED. {‘error’: {‘code’: 429, ‘message’: ‘You exceeded your current quota, please check your plan and billing details. For more information on this error, head to: [The link]. To monitor your current usage, head to: [other link]. ‘, ‘status’: ‘RESOURCE_EXHAUSTED’, ‘details’: [{’@type’: [Link], ‘links’: [{‘description’: ‘Learn more about Gemini API quotas’, ‘url’: [link]}]}]}}

That happened on a BRAND NEW API KEY ON A BRAND NEW PROJECT, after not using any api key for 24 hours. What’s more, I have 4 google accounts (3 of them for business puproses and 1 for personal use). Only one of them is allowed by google to create API keys, while when I try with the 3 others, it gives me a very vague error message and tells me it’s either because they are underaged (which they aren’t) or because api keys aren’t allowed in my region (I’m in France, so pretty sure that’s not the case).
Lastly, one of these 4 accounts was recently flagged as suspicious of being a bot. I made an appeal and turns out google gave me back the account and apologized for suspecting.

Now for the API keys:

At some point, I used a lot of quota (around 50 requests per day to gemini flash) in order to develop an app and try to understand how it works. Now, I’m barely using it to give 7 requests a day to gemini flash.

Lastly, before anyone tells me about projects, I have one key per project and recently I’ve only been using one of them.

Is this some sort of shadow banning? Is there any way to contact google and explain to them that I am not a bot and trying to use their API keys for evil, but simply using them to generate 5 fun facts per day?

Sorry for my english as I am not a native speaker, and thanks for the answers!

Hi @stan2307
Welcome to the Google AI Forum!!!

Could you please confirm whether billing is enabled for the project associated with this API key, and the account is currently on a free tier or a paid subscription?

Thanks!

Hello! Thanks for the answer. Billing isn’t enabled, and it’s on free tier. I’m using text-generation models, no image or whatsoever.

Hello,

Thank you for bringing this to our attention. Could you please share the full payload details along with a sample of the code that you are using? We would like to reproduce the issue.

Thanks!
