Google AI Studio creates Gemini API keys tied to a Google Cloud project. Free-tier eligibility depends on model, region, and current quota.
Get the API key
- Open Google AI Studio API Keys and sign in.
- Choose Create API key and select or create the intended Google Cloud project.
- Copy the generated key and store it securely.
Use the key on Free AI API
Paste the key into the API Key field on a Google AI Studio endpoint page and run the request.
Review the current Gemini API rate-limit page before production use; free-tier availability varies.
Security: never publish the key. Free AI API forwards it for the current request and does not store it on the server.
