- Go to Google One -> Google AI to start your Google AI Pro subscription free trial which will give you access to `Veo 3` in Gemini.
- Go to Google AI studio to create your API key, and also to Google Cloud Console to enable Billing.
- Attach an `Http Request` node after the Video Prompt Generator node and use the `Gemini API` documentation to find the Endpoints so choose REST among the options (python, javascript ...) and copy the curl command to import into the Http Request node. Don't forget to turn on Expression for the body instead of sending fixed since `{{ JSON.stringify($json.output) }}` should be parsed.
