Hello, I would like to ask for help regarding a persistent Gemini API access issue.
This issue persists even with brand new projects, brand new API keys, and the official minimal Gemini API test.
Problem
When I run the official minimal API test, I consistently receive the following error:
What I already tried
I have already tested the following:
-
Created a completely new Google Cloud project
-
Created a completely new Gemini API key in Google AI Studio
-
Used the official minimal API request with gemini-2.5-flash
-
Tested outside of any third-party plugin or application
-
Verified that my network exit region is Japan
-
Retried with fresh projects and fresh API keys
Additional context
My Google account region is Japan.
I also tested with a Japan exit IP, and the IP location resolves to Tokyo, Japan.
Despite this, the same error still occurs for the minimal API request.
Why I believe this is not a normal configuration issue
This issue still happens even with:
-
brand new projects
-
brand new API keys
-
the official minimal API test
-
a supported region network exit
So this does not appear to be caused only by:
-
plugin configuration
-
old project settings
-
model name mismatch
-
ordinary rate limits
Request
Could someone please help check whether this may be caused by:
-
an account-level restriction
-
eligibility verification issues
-
automated risk-control review
-
or another backend access denial related to Gemini API
Since the same error persists across brand new projects and brand new API keys, this appears to be an account-level or backend access issue rather than a normal project configuration problem.
Thank you very much.
