Sketch to render API
Send a hand sketch, a massing model or a viewport screenshot with a few words on materials and light. The engine keeps the geometry of the drawing and renders the rest as a finished image.

Keeps the drawing
The lines, openings and massing of the sketch stay; the engine fills in materials, light and context.
Follows references
Add images to follow for style, a material, the atmosphere, a colour or the geometry.
Exteriors and more
Render as an exterior, an interior, a masterplan, a landscape, a plan or a product.
Repeatable
Reuse a seed to stay close to a result you liked while you change the prompt.
Start with a single call
Every call returns a job. Poll it, wait on it, or add a webhook and hear when it settles. The SDKs for TypeScript, Python, PHP, Go and .NET send the same request.

Questions
Does the render follow my sketch?
Yes. The engine keeps the geometry of the drawing. A loose sketch takes more interpretation, so say in the prompt what the lines are, such as a timber screen or a glass corner.
Can I render from a 3D viewport?
Yes. Export the viewport as an image and send it like a sketch. The plugin guide shows the whole loop: export, render, bring the image back.
What images can I send?
Send the image as a public link, as base64, or as the file itself in a multipart request: JPEG, PNG or WebP up to 15 MB. No upload step comes first.
How is it priced?
Prepaid, pay as you go. Top up any amount from $10 to $5,000 and each call draws its listed price from your API wallet. Your first top-up adds $5 free. There is no subscription.
Start rendering from your own product.
Top up from $10, and your first top-up adds $5 free. The same account signs you in to Studio and the API.
