For filtering nude images and videos, you can use the following free APIs:
Eden AI: Eden AI offers a free trial with $10 in credits to start. It provides explicit content detection in images and videos, including nudity, sexual activity, and other inappropriate content.
Azure AI Vision: Azure AI Vision offers a free tier with limited requests. It can detect adult content in images, including nudity, and returns a score between 0 and 1 to indicate the likelihood of explicit content.
Cloud Vision API: The Cloud Vision API by Google provides a free tier with limited requests. It includes a SafeSearch detection feature that flags inappropriate images, including those with nudity, and returns likelihood values for different categories of explicit content.
These APIs can be integrated into your application to filter out nude images and videos.
