Antigravity CLI 1.2.5: Eligibility check fails after successful authentication and age verification

Google Antigravity
1

I cannot use Antigravity CLI because the eligibility check keeps failing.

Environment:

  • Windows 11
  • Antigravity CLI 1.2.5
  • Personal Gmail account
  • Google OAuth login
  • Google age verification page shows that my age is verified
  • Google Terms of Service country version shows Japan

Error:
“Your current account is not eligible for Antigravity. Verify your account to continue.”

What I tried:

  1. Opened the verification URL provided by the CLI.
  2. Completed the browser authentication, which showed “Authentication successful.”
  3. Confirmed that the browser and CLI use the same Google account.
  4. Confirmed my age verification status.
  5. Restarted the CLI, but the same error remains.

Could you advise on the next troubleshooting steps and how to request a private account eligibility review if needed?

Thank you.

Hi @automation_user917, Welcome to the Forum,

This happens on Windows 11 because the Antigravity CLI caches your initial token in Windows Credential Manager and local disk storage; restarting the CLI silently reloads that stale, unverified session instead of re-checking your eligibility with Google.

Could you please follow these steps:

  • Clear out the saved credentials:

    • Open your Start menu, search for Credential Manager, and click on Windows Credentials. Look under Generic Credentials and remove any entries for Antigravity CLI or agy.

    • Open PowerShell or Command Prompt and wipe the local session cache folder:

      rmdir /s /q "%USERPROFILE%\.gemini\antigravity-cli"

  • Run agy again in your terminal. When it generates the browser sign-in link, copy and paste it into an InPrivate / Incognito window. This ensures it doesn’t accidentally grab credentials or cookies from another Google account logged into your browser.

  • Even if the Terms of Service page lists Japan, Google’s eligibility system often checks the region set in your Google Payments Settings. Make sure you don’t have an older payment profile or address pointing to an unsupported country.

  • You can actually bypass the account eligibility check completely by using a free API key from Google AI Studio. Just add "modelProvider": "gemini" inside %USERPROFILE%\.gemini\antigravity-cli\settings.json, export $env:GEMINI_API_KEY="your-key" in PowerShell, and launch agy.

  • If it’s still blocking you after clearing the cache, you can submit a request through Google’s Country Association Form to have your account’s region corrected, or reach out through Antigravity Support.

Let us know if clearing the Credential Manager entries gets you past the screen!

Update after testing the suggested credential reset:

  • I removed only the gemini:antigravity entry from Windows Credential Manager.
  • I preserved the local Antigravity cache, conversations, and settings.
  • I launched Antigravity CLI again and completed a fresh Google OAuth sign-in.
  • The CLI now reports version 1.2.6 and recognizes the signed-in account and available model.
  • Immediately afterward, the same eligibility check fails before any prompt is sent.

I also verified the published eligibility conditions in the official Antigravity FAQ:

  • Personal Gmail account
  • Age verification completed and over 18
  • Google account country association is Japan
  • Japan is listed as a supported Antigravity country

The Google Country Association Form already shows Japan, so a region-change request would not be appropriate. I did not use an API-key bypass and did not delete the entire local cache.

Could an Antigravity staff member review the backend eligibility state for this account, or provide a private support path for an account-specific review?
