Hello

Hello @Mahbubur_Rahman ,

Project 31844079... is active on Tier 1 with billing enabled, but our logs show 0 API requests recorded under this project. This might happen when your application is making calls with an API key tied to a different, unbilled project. API keys inherit the quota tier of the specific project they belong to.

Next steps:

  • Open your API keys in Google AI Studio.
  • Verify that your active API key is provisioned under project 31844079... (gen-lang-client-061548...).
  • If your current key belongs to a different project, create a new API key for project 31844079... and update your application.
  • If you still face issues, let us know.
