Every platform that accepts user-uploaded images faces the same challenge: how do you keep explicit content from reaching your users?

Manual review is expensive, slow, and mentally taxing for moderators. An NSFW detection API solves this by classifying images in milliseconds, letting you enforce content policies at scale.

Instead of a binary block/allow, use confidence thresholds:

This dramatically reduces false positives while catching what matters.

Send an image URL, get back classification labels with confidence scores:

Plug the API into your upload pipeline so every image is classified before it reaches the feed. Pair it with face detection for a comprehensive safety stack.

Prevent sellers from uploading inappropriate product thumbnails. Keeps your platform compliant with payment processor policies.

Dating apps face disproportionately high rates of explicit content. Run every uploaded image through the pipeline in real time. Customize thresholds: stricter for public profiles, more relaxed for age-verified private messaging.

Scan attachments in chat messages, shared whiteboards, and document uploads. Classification happens in under a second — users experience no delay.
