Vectorize

Converts a raster image into an editable vector file.

POST https://patentfig.ai/api/v1/vectorize

Cost: 20 credits per call.

Image input

Two forms, shared by all image-accepting endpoints:

• JSON body with imageUrl — a publicly reachable URL, or
• multipart/form-data with a file field.

Accepted formats: PNG, JPEG, WebP, TIFF. Max 10 MB.

Parameters

Choosing an engine

• lineart — AI redraws the figure as clean single-stroke patent line art. Each drawn line becomes one path, which is what makes DXF usable in CAD. Best for patent figures.
• trace — traces the input pixels faithfully, preserving fills and shading. Best when the vector output must match the original image. Note: trace produces filled outlines, so DXF output may contain double lines — prefer lineart for CAD.
