There are two results in reponse.
enable_nsfw_detection
, when return with true
means NSFW detection is enabled.
nsfw_detection_result
, presenting an array of NSFW detection outcomes for each image. The order of elements in the nsfw_detection_result array corresponds one-to-one with the sequence of images in the images
field in the response. The valid
field denotes the success of the NSFW detection process, while the confidence
field, ranging from 0 to 100, signifies the confidence level of the NSFW detection result. Higher confidence values, nearing 100, suggest a greater likelihood of the corresponding image containing NSFW content.
