AI Image Detection Response

The Copyleaks AI Image Detection API returns a detailed response containing the analysis summary, image information, and a Run-Length Encoded (RLE) mask to identify AI-generated regions.

Response Properties

string

The version of the AI detection model used for the analysis.

object

Contains the Run-Length Encoded (RLE) mask data. This can be used to visualize the AI-detected regions of the image.

Show properties

array<integer>

An array of starting positions for each AI-detected segment in the flattened 1D image array.

array<integer>

An array of lengths for each AI-detected segment, corresponding to the starts array.

object

An object containing the overall proportion of human vs. AI-generated pixels.

Show properties

float

The proportion of the image determined to be human-created. The value ranges from 0.0 to 1.0.

float

The proportion of the image determined to be AI-generated. The value ranges from 0.0 to 1.0.

boolean

Indicates whether the image was determined to be AI-generated.

object

An object containing metadata about the analyzed image.
