You are building an app that will enable users to upload images.

Generate alt textTo automatically suggest descriptive captions for images (usable as alt text), use the Computer Vision Describe Image API. It returns natural-language captions summarizing the image content. Endpoint: /vision/v3.2/describe. Setting maxCandidates=1 gives a single best caption.

Detect inappropriate contentTo block adult/racy/gory images with minimal effort, use Computer Vision Analyze Image with the Adult visual feature. This returns flags (isAdult, isRacy, isGory) and confidence scores. The provided option includes Adult,Description which still returns the needed adult/racy/gore signals, satisfying the requirement.

These choices minimize development effort by using built-in Computer Vision capabilities without training a custom model or wiring up multiple services.
