Turn 3D files into finished images
3D File Image Prompting API
Place any 3D object into a generated scene with one API call. Upload a GLB file, describe the scene in a prompt, and the API renders your object into it. Control the aspect ratio.

How it works
No pipeline to build, no models to configure.
Send the GLB file and a prompt
POST a URL to your 3D model plus a prompt describing the scene. Add an aspect ratio (1:1, 16:9, 9:16, 4:3, or 3:4) when you need a specific format.
AI renders and composites
The workflow renders your 3D object and builds a scene from the prompt around it, matching lighting and perspective so the object sits naturally in the frame.
Get the finished image
Receive the rendered image inline, or via webhook when you pass a callback_url. Ready for catalog, campaign, or marketplace delivery.
Your real 3D asset, rendered in
A text-to-image model guesses an object from words and rarely matches a real product. The 3D File Image Prompting API renders your actual GLB file, so the object in the output keeps the geometry, proportions, and detail of your asset. The model only builds the world around it.
Scenes built from a text prompt
Describe the environment and the API generates it around your object. Lighting and perspective are matched to the placed model, so the object reads as part of the scene instead of sitting on top of it. Change one prompt to ship the same product in a studio, a rainforest, or a city street.
One endpoint for catalog and ad work
Run it on every 3D asset that needs finished imagery, from product SKUs to game props. One call returns a rendered image, and async webhook delivery drops it into a generation or creative pipeline.
3D File Image Prompting for every imagery workflow
Wherever you have a 3D file but need a finished image, this is the layer that gets you there.
Product teams with 3D assets
Turn the GLB files you already have into finished product imagery without a photo shoot or a render farm. Place a SKU in any scene your campaign needs.
Ad creative teams
Ship one product across a dozen scenes for paid social, display, and DCO. Change the prompt, not the asset, to test backgrounds and concepts fast.
3D and game studios
Render props, characters, and items from your engine assets into marketing scenes. The model stays accurate while the world around it changes.
Marketplaces and catalogs
Generate consistent product imagery from seller-supplied 3D files so listings look finished without a studio.
Working with Runflow changed how we build. Our developers can integrate a new AI feature by calling an endpoint, they don’t need machine learning expertise, infrastructure knowledge, or DevOps skills. We just focus on making the best product, and Runflow handles everything underneath.
Your data stays yours
Images are processed in isolated environments with automatic cleanup. Zero data retention by default.
SOC 2 Type II compliant.
