Hello Google AI Studio team, I am using Google AI Studio with a paid Gemini API project and prepaid billing. Veo 3.1 Fast was previously working correctly for me and I successfully generated several videos. Now every new video generation request returns: **“Failed to generate video: permission denied. Please try again.”** I have tried Veo 3.1 Fast and Veo 3.1. The error persists. My project is paid and AI Studio confirms that I am using a paid API key. This is a legitimate low-volume creative project for testing short marketing/lifestyle videos. Could you please check whether there is an access restriction, entitlement issue, or automated security flag on my project and restore Veo access if this is a false positive? I can provide my project ID, screenshots, timestamps and other diagnostic information privately if needed. Thank you. ---

Update with additional diagnostic evidence (8 September 2026): - Google AI Studio recognizes the project as Paid Tier 1 with active prepaid credit. - The Gemini API ([generativelanguage.googleapis.com](http://generativelanguage.googleapis.com)) is enabled. - The Rate Limit page explicitly lists Veo 3 Generate, Veo 3 Fast Generate, and Veo 3 Lite Generate, each with available limits of 2 RPM and 10 RPD. Usage is 0, so this is not quota exhaustion. - The Projects and Billing pages show the correct project and billing account, with no actionable warning or appeal banner. - Following the troubleshooting advice given in a similar thread, I attempted to create a fresh API key in AI Studio for the same project. That request was rejected immediately with: “Failed to generate API key. The request is suspicious. Please try again.” This new result strongly suggests an automated security/trust flag affecting AI Studio or the account/project control plane. The Veo request is also rejected before it is recorded in usage. Could a Google AI Studio / Gemini API team member please initiate a manual Trust & Safety review and remove the restriction if this is a false positive? I can provide the project ID, billing account reference, timestamps, and screenshots privately to a Googler. I will not publish API keys. Thank you. ---

Hello @dd26f32a546b13cf02c9@Javier_Berrocal_Tade , DM’ed you for details. ---

Hello @Javier_Berrocal_Tade , Could you also confirm that the below verifications are done. If not done, please do so and retry creating a new api key linked to your billing-linked project and retry API requests. Just want to rule out any edge cases, Thanks! Visit [Google Account Security](https://myaccount.google.com/security) and ensure [Phone Verification](https://myaccount.google.com/phone), [2-Step Verification (2SV)](https://myaccount.google.com/signinoptions/twosv), and [Age Verification](https://myaccount.google.com/age-verification) (under [Birthday](https://myaccount.google.com/birthday)) are completed and enabled on the Google Account linked to your AI Studio project. If you still get the same error, please let us know. ---

Hello Pooja, I have completed the requested checks for the Google Account linked to the AI Studio project: - Phone verification is completed. - 2-Step Verification is enabled. - The Google age-verification page confirms that no further age verification is required for this account. I then retried creating a new API key in Google AI Studio, explicitly linked to the billing-enabled project: Project ID: gen-lang-client-08959428.. Project name: Default Gemini Project Billing tier: Paid Tier 1 — Prepaid The request still fails immediately with the exact error: “Failed to generate API key. The request is suspicious. Please try again.” Therefore, the issue persists after completing all requested account-security checks. Could you please escalate this for a manual review of the account/project restriction or automated Trust & Safety flag? Thank you. ---

Hello @Javier_Berrocal_Tade, The error could have been triggered by browser-side anti-automation checks instead of an account restriction (as your account is already on paid tier 1). Please try using a different browser or incognito window, closing browser developer tools (DevTools), disable suspicious browser extensions or custom user-agent overrides, and try generating a new key in a clean browser window. ---

I have the same problem. I’m also using a paid Tier 1 account and get the same error message. I’ve completed age verification, two-factor authentication, and phone verification. Even using the Chrome browser in incognito mode with all extensions disabled didn’t help. ---

I was able to “fix” the problem by creating a new API key. I don’t understand why the old “default” key caused this problem for me and many others. ---

Update: the issue is now resolved. Following the suggestions in this thread, I opened a clean Chrome Incognito session with extensions and DevTools disabled. In that session I was able to create a new Gemini API key for the same billing-enabled Paid Tier 1 project without receiving the previous “suspicious request” error. I then linked and saved the new key in my normal Google AI Studio session. Veo 3.1 successfully generated a video, and AI Studio now confirms that the new key is active. One detail: during testing, video generation also succeeded once while AI Studio still appeared to reference the previous key. Therefore, I cannot confirm whether creating the new key itself fixed the problem or whether a temporary browser-side/security restriction cleared at the same time. What I can confirm is that PERMISSION\_DENIED is no longer reproducible and Veo video generation is working normally. Thank you @Pooja_Kapse and @no6mis for the help.
