To begin using Google Imagen 4 and Imagen 4 Ultra through Kie.ai, first create an account on the platform. Once registered, access the API dashboard where you can generate your unique API key. This key is essential for authenticating requests and unlocking the advanced functionalities of both the Imagen 4 API and the Imagen 4 Ultra API.

Step 1: Obtain Your Google Imagen API Key

When configuring your API call, you will need to provide several key parameters. The prompt is required and serves as the main textual description of the image you want to generate. You may also include a negative_prompt to exclude unwanted elements, specify an aspect_ratio to control image dimensions, set num_images to generate multiple variations in one request, and use a seed to reproduce consistent results. Choosing the appropriate combination of these inputs ensures you receive outputs aligned with your creative or professional needs.

Step 2: Configure Your Google Imagen API Request

Once your request parameters are ready, submit them via a POST request to the designated Imagen 4 or Imagen 4 Ultra endpoint. Include your API key in the authorization header, and place your configured parameters in the request body. Kie.ai handles the request routing seamlessly, allowing you to focus on refining prompts and achieving the best possible output from the model.

Step 3: Submit the Imagen API Request

After submitting your request, you will receive a task ID that allows you to track progress. Use this task ID with a GET request to check the generation status. Once completed, you can download the generated image directly or integrate it into your application. By iterating on your prompts and optional parameters, you can fine-tune results and fully leverage the creative power of Google Imagen 4 and Imagen 4 Ultra APIs on Kie.ai.

Step 4: Monitor and Retrieve Results

Step-by-Step Integration of Google Imagen 4 API and Imagen 4 Ultra API via Kie.ai

When working with Imagen 4 API, adding precise details in your prompt helps achieve highly relevant outputs. For example, instead of writing “a cat in a room”, describe “a white Persian cat sleeping on a vintage armchair in a warmly lit library.”

Detailed Prompt Engineering with Imagen 4 API

The Imagen 4 Ultra API is particularly strong at handling diverse styles such as photorealism, impressionism, or surrealism. Include style references directly in your prompt—for example, “a futuristic city skyline in the style of cyberpunk.”
