How to Integrate Nano Banana Pro API into Your Projects
Step 1: Get Your Nano Banana Pro API Key
To begin using the Nano Banana Pro API, the first step is to obtain your Nano Banana Pro API Key. Visit the API Key Management Page to generate your unique key. This key will be required for all API requests, allowing you to authenticate and securely interact with the service. Simply include your API key in the request header using the format: Authorization: Bearer YOUR_API_KEY. This ensures that each request is properly authenticated and linked to your account.
Step 2: Create a Generation Task
Once you have your Nano Banana Pro API Key, the next step is to create a generation task. This involves sending a POST request to the createTask endpoint. In this request, you’ll need to specify the model (nano-banana-pro), provide an input object that includes a prompt for the image you want to generate, and optionally set parameters like resolution and aspect ratio. The API will return a taskId that you can use to track the status of your request.
Step 3: Monitor Task Status
After submitting your generation task, you can monitor its progress by querying the task status. You can do this by making a GET request. This will provide the current status of the task (whether it's still waiting, completed successfully, or failed). If you provided a callBackUrl in your task creation request, you will automatically receive a notification when the task is complete. Otherwise, you can periodically check the status until the task is finished.
Step 4: Retrieve and Use Your Results
Once your task has successfully completed, you can retrieve the results. If the task state is success, the results will be included in the response under resultJson. You can use the provided URLs for the generated images in your application, whether for websites or other visual content. These images will be generated with the high-quality output you requested, ready for immediate use in your projects.
Why Nano Banana Pro API is the Right Choice for Your Projects?
