Hello Google Gemini API Team,
I am experiencing a Gemini API quota issue with a Paid Tier 1 project.
Project information:
- Project ID: gen-lang-client-00715427..
- Project Number: 1544002806..
- Billing/Tier: Tier 1
- Model: gemini-3.1-flash-image (Nano Banana 2)
AI Studio currently shows the following limits for Nano Banana 2:
- RPM: 100
- TPM: 200K
- RPD: 1K
However, actual Gemini API requests consistently fail with HTTP 429 RESOURCE_EXHAUSTED.
The important part of the error is:
quota_metric:
generativelanguage.googleapis.com/api_requests
quota_limit_value:
0
quota_location:
asia-east1
The same quota error also occurs with a simple GET request to:
/v1beta/models
Therefore, this does not appear to be related to image generation, the prompt, or the specific image-generation endpoint.
The project number returned in the API error is also:
1544002806..
This is the same project number associated with the Tier 1 project shown in AI Studio.
Expected behavior:
The project is Tier 1 and AI Studio shows a non-zero quota for Nano Banana 2.
Actual behavior:
The API appears to apply an api_requests quota of 0 in asia-east1, resulting in HTTP 429.
Could you please check whether the api_requests quota for project 1544002806.. is incorrectly provisioned or synchronized?
In particular, could you verify why:
- AI Studio shows Tier 1 with valid model quotas
- but the Gemini API returns api_requests quota_limit_value=0
- and the request is routed to asia-east1?
I have not exceeded the displayed model limits.
Thank you.
