Description:
I am experiencing consistent 403 errors when trying to use any Gemini model (e.g., google/gemini-3-flash-preview) through OpenRouter.
The problem occurs right after I added funds to my account – as soon as I start making requests to Gemini, I receive the error:

PROXY ERROR 403: {"error":{"message":"Blocked by Google AI Studio","code":403,"metadata":{"provider_name":null},"user_id":"user_39HaQkvFNCwyMPIRscRBovatqWu"}}

Other models (like Claude) work without issues.
I rely on Gemini for my projects, and this block prevents me from using the service I paid for.

What I've Tried:
· Tried different Gemini prompts and endpoints.
· Confirmed that the issue is specific to Gemini models.
· Verified that my internet connection is stable and no VPN is active.
· Waited and retried after some time – the error persists.

Error Messages:

PROXY ERROR 403: {"error":{"message":"Blocked by Google AI Studio","code":403,"metadata":{"provider_name":null},"user_id":"user_39HaQkvFNCwyMPIRscRBovatqWu"}}

API/Model: google/gemini-3-flash-preview

Thank you for the detailed information. To help the mods and support team debug this Gemini access issue, I need a bit more context:

  1. Are you using your own Google API key (BYOK), or are you accessing Gemini via OpenRouter’s provided API access?
  2. Can you confirm the exact request payload (minus any sensitive info) you are sending to the /chat/completions or /completions endpoint?
  3. Is this issue happening with only google/gemini-3-flash-preview, or do you see the same 403 error with other Gemini models (e.g., google/gemini-3-pro-preview, google/gemini-2.5-flash)?

These details will help us pinpoint whether this is a provider block, API misconfiguration, or something else. Please reply with this information so we can assist further.

  1. I am accessing Gemini through OpenRouter's provided API, not using my own Google API key (BYOK).
  2. The request is sent to the /chat/completions endpoint.
  3. The 403 error "Blocked by Google AI Studio" occurs with all Gemini models I have tried:
    · google/gemini-3-flash-preview
    · google/gemini-3-pro-preview
    · google/gemini-2.5-flash
    Other non-Google models (like Claude, GPT) work fine—the issue is specific to the Google/Gemini provider.

Additional details:

· My OpenRouter user ID: user_39HaQkvFNCwyMPIRscRBovatqWu
· The error appears immediately after I topped up my balance.

Thank you for the detailed answers. Since you are:

  • Using OpenRouter’s provided API (not BYOK)
  • Experiencing 403 "Blocked by Google AI Studio" errors across all Gemini models (e.g., google/gemini-3-flash-preview, google/gemini-3-pro-preview, google/gemini-2.5-flash)
  • Able to use other non-Google models without issue
  • Seeing the error immediately after topping up your balance

There is no relevant documentation that explains this specific scenario or error. The 403 "Blocked by Google AI Studio" suggests an upstream block or restriction from the provider, not a misconfiguration in your request.

For account-specific or billing-related issues (including access being blocked after a top-up), you need to contact OpenRouter support directly. As per Discord server policy, please email [email protected] with your account details and a description of the issue. Billing and account issues are not handled on Discord.

For reference:

  • "For any cases where there is an account or billing issue, direct users to email [email protected]. We do not handle billing issues on Discord."
  • "For any technical questions, API issues, or model issues, email support is not available for free tier accounts or accounts that have spent less than $10. Essentially, emails sent to [email protected] from accounts with <$10 spend will be redirected to Discord."

If you have spent $10 or more, please email [email protected] so the team can investigate your account and resolve the block.

If your account has not met the $10 spend threshold, you will need to continue troubleshooting in Discord with the mods.

I don't have specific documentation for this exact issue. Please confirm your spend and contact support as describ...
