The detection and filtering of inappropriate content, such as nude images, is a critical aspect of online protection for businesses and their users. A Nudity Detection API is an application programming interface that uses machine learning and computer vision to detect and filter out unwanted content in images. These APIs are used by developers to integrate with mobile applications and websites to protect users from adult and sensitive images. Companies use these APIs to provide online protection for their users and customers, which can help prevent adverse reactions, low SEO rankings, and loss of customers due to NSFW (Not Safe For Work) content. The detection accuracy and pricing plans vary among the top Nudity Detection APIs, including Inferdo, Netspark's Nude Detect, Microsoft Content Moderator, Eyerecognize's Nudity Recognition, Sightengine's Nudity Detection- Nudity and adult-content filter for images, Adult Image Detection, NSFW Classification, ClarifaiPublicModels, Deep NSFW Detect, and Nudity Image Detection (NSFW) using Deep Learning Models.
