Authorizations

​
Authorization
string
header
required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

Upscale or enhance an image based on the supplied parameters. Using a scale of 1 with enhance enabled will only run the enhancer.

​
image
required

The image to upscale. Can be either a file upload or a base64-encoded string. Image dimensions must be at least 65536 pixels and final dimensions after scaling must not exceed 16777216 pixels.

​
enhance
default:false

Whether to enhance the image using Venice's image engine during upscaling. Must be true if scale is 1.

Example:

true

​
enhanceCreativity
number | null
default:0.5

Higher values let the enhancement AI change the image more. Setting this to 1 effectively creates an entirely new image.

Required range: 0 <= x <= 1
Example:

0.5

​
enhancePrompt
string

The text to image style to apply during prompt enhancement. Does best with short descriptive prompts, like gold, marble or angry, menacing.

Maximum length: 1500
Example:

"gold"

​
replication
number | null
default:0.35

How strongly lines and noise in the base image are preserved. Higher values are noisier but less plastic/AI "generated"/hallucinated. Must be between 0 and 1.

Required range: 0 <= x <= 1
Example:

0.35

​
scale
number
default:2

The scale factor for upscaling the image. Must be a number between 1 and 4. Scale of 1 requires enhance to be set true and will only run the enhancer. Scale must be > 1 if enhance is false. A scale of 4 with large images will result in the scale being dynamically set to ensure the final image stays within the maximum size limits.

Required range: 1 <= x <= 4
Example:

2
