Account restricted to AQ. tokens — requesting AIza API key restoration (project 4827898502..)

Gemini API

My account can no longer generate standard AIza-format API keys. Every key I create
(across projects) is issued in the new AQ. format, and these tokens fail against the
Generative Language REST API with:

401 UNAUTHENTICATED — "Request had invalid authentication credentials.
Expected OAuth 2 access token, login cookie or other valid authentication credential."
reason: ACCESS_TOKEN_TYPE_UNSUPPORTED
method: google.ai.generativelanguage.v1beta.GenerativeService.GenerateContent

Affected project:

  • Project name: cutevideo-2
  • Project number: 4827898502..

I believe this restriction was applied automatically after a past key-exposure flag.
I have since:

  • Deleted/revoked all old API keys in AI Studio and the Cloud Console,
  • Moved all secrets to a local .env file (environment variables) that is gitignored
    and was never committed to version control,
  • Verified no keys remain exposed in any public repository or paste.

Could you please review my account and restore the ability to generate standard
AIza-format API keys? Happy to provide any additional information needed.

Thank you.

Hi, We are moving away from Traffic keys (Alza) and towards a more secure Authentication Key (AQ). AI Studio will now only generate Authentication Key (AQ) keys. More information on key usage can be found in the Using Gemini API keys documentation.

Please submit any compatibility issues with services / SDKs etc. in this form for our engineering team to review. Thanks!
