Advanced Customization Options

Building on the basics of integration, advanced customization options allow developers to tailor virtual staging in ways that align with specific market needs and client preferences.

Text-Prompt Design Generation

The parameter takes natural language descriptions and turns them into detailed, photorealistic designs. By entering a custom text prompt, developers can override default settings like , , and . This gives complete control over the final output. For instance, a developer might input: "A modern minimalist living space with Scandinavian influences, featuring clean lines, natural materials, and abundant natural light" to create a design that perfectly matches that description.

For even greater precision, setting higher values (above 15) ensures the design adheres closely to the text prompt. Additionally, the parameter makes it possible to replicate results by using the same prompts and parameters multiple times.

Pairing text prompts with the parameter takes customization further. This combination allows developers to specify exact furniture placement using JSON strings that include image URLs and item descriptions.

Fine-Tuning Design Elements

Decor8 AI's API gives developers granular control over design details through specialized endpoints that cater to preferences common in the US market. For example, the "Remove Objects from Room" endpoint can clear out furniture while keeping architectural features like walls, windows, and built-ins intact.

Color customization is also highly flexible. Developers can apply trending paint palettes or brand-specific colors by using precise hex codes through endpoints dedicated to wall colors and kitchen cabinets. These adjustments maintain realistic lighting and shadows, ensuring the staging remains visually convincing.

For clients inspired by specific aesthetics, the feature allows users to upload reference images. The system can then adapt those design elements into the staging project. This is especially useful for real estate agents working with buyers who have a clear vision for their dream property.

Other advanced controls include the parameter (range 0-1, default 0.39), which adjusts the level of variation in designs, and the parameter (range 1-75, default 50), which balances quality and processing speed.

Batch Processing and Real-Time Features

Managing large-scale virtual staging projects becomes easier with asynchronous request handling, enabled by configuring the parameter. This setup efficiently processes large batches of staging requests across multiple properties.
