How to get Gemini API Key

To get a Gemini API key:

1. Sign in to Google Cloud Console: https://console.cloud.google.com/
2. Create or select a project: use the project dropdown → New Project (or choose an existing project).
3. Enable the Gemini API: Console → APIs & Services → Library → search for "Gemini API" and click Enable.
4. Create an API key: Console → APIs & Services → Credentials → Create Credentials → API key.
5. Secure the key:

• Restrict the key by application type (HTTP referrers, IP addresses, or Android/iOS apps).
• Restrict the key to the Gemini API via API restrictions.
• Store keys in environment variables or a secure secret manager; do not commit them to source control.

6. Test and rotate:

• Follow the Gemini API documentation for request examples and where to include the key.
• Regularly rotate keys and revoke unused keys.

Note — Billing and quotas

• Google Cloud APIs are paid services; enable billing for the project to avoid interruptions.
• New users may receive a free trial credit (check the console for current offers and terms).
• Configure budgets, alerts, and quota monitoring in Billing → Budgets & alerts to avoid unexpected charges.
• Review quota limits for the Gemini API and request increases if needed.

For exact request formats and SDK examples, see the official Google Cloud / Gemini API documentation in the Cloud Console.
