Account restricted to AQ. tokens — requesting AIza key restoration

Gemini API
, ,
1

Hello Google AI Developer Support Team,

My account can no longer generate standard AIza-format API keys. Every key I create in Google AI Studio — including keys in newly created projects — is issued with an “AQ.” prefix instead.

When I use these AQ. keys to call the Gemini API (generativelanguage.googleapis.com, generateContent), every request fails with:

401 UNAUTHENTICATED — “Request had invalid authentication credentials. Expected OAuth 2 access token…” (reason: ACCESS_TOKEN_TYPE_UNSUPPORTED)

Project details:

  • Project number: 6036065040..
  • Project ID: gen-lang-client-01128177..

What works: the key authenticates for models.list (returns the model list normally).
What fails: generateContent / image generation — always 401.

I have checked my public repositories and found no exposed API keys. I have not intentionally shared any key.

Could you please restore my account’s ability to generate standard AIza-format keys? Thank you.

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!
