API Key Created!

You can now use this key to call the Gemini API. Google Gemini has a generous free tier for testing and development.

Keep your API key secure and never share it publicly. If you accidentally expose it, you can delete and create a new one. Store it in a password manager or environment variable.
Google Gemini has a free tier with generous quotas for API usage. You can monitor your usage and set quotas in the Google Cloud Console to avoid unexpected charges.

Happy building with Google Gemini! 💎
