Request body

Submit an async generation request. The model field selects the model; other fields are model-specific input parameters.

stringmodelrequired

Model identifier. Set to fashn/tryon/v1.6.

Default: fashn/tryon/v1.6

Optional<string>output_format

Output format of the generated images. 'png' is highest quality, while 'jpeg' is faster

Optional<string>model_image

URL or base64 of the model image

Optional<string>garment_photo_type

Specifies the type of garment photo to optimize internal parameters for better performance. 'model' is for photos of garments on a model, 'flat-lay' is for flat-lay or ghost mannequin images, and 'auto' attempts to automatically detect the photo type.

Allowed values: auto, model, flat-lay

Default: auto

Optional<boolean>segmentation_free

Disables human parsing on the model image.

Default: true
