Explanation:
Generate alt text
To 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 content
To 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.
