I’m having an issue with the Gemini API quota on one specific Google Cloud project.
-
Project ID:
fabled-pivot-474606-j8 -
Project name:
gemini cli -
Billing: The project is linked to a valid billing account and billing is active.
-
API:
Generative Language API (generativelanguage.googleapis.com)is enabled for this project. -
Permissions: My account has sufficient IAM permissions on the project (Owner / Editor + billing access).
Symptoms:
-
In Google AI Studio → Gemini API Usage for this project, I see a banner:
“Project quota tier unavailable. Please contact your project administrator for assistance.”
All usage charts show “Error loading data”. -
Any Gemini API request made with an API key from this project immediately returns HTTP 429 RESOURCE_EXHAUSTED, even for the very first request.
-
However, another project under the same Google account and the same billing account (for example, project
cherry-studio) shows a normal Free quota tier in AI Studio, and API keys from that project work fine.
Because another project with the same billing account works normally, it looks like the issue is specific to the gemini cli project. From the outside it seems that this project might not have any Gemini quota assigned (possibly a producer override or some internal configuration issue), so AI Studio shows “quota tier unavailable” and all calls return 429.
