What is an Image Moderation API?

Image Moderation detects and filters unwanted content such as written texts, faces, and objects from images and videos. It is mainly used to moderate adult-only content that is generally inappropriate for people under the age of 18 that includes NSFW (Not Safe For Work) occurrences: nudity, sexual activity, profanity, or any type of violence.

In addition to inappropriate content, it can also be used to detect fraud to block scammers, personal information (phone numbers, emails, social security numbers), minors, or even the presence of celebrities.

The Image Moderation API predicts whether an image contains potentially explicit content based on a probability score between 0 and 1. It also returns a determination of whether the image meets the conditions (true or false).

Examples of Image Moderation tasks


Image Moderation APIs can detect degrees of nudity: from partial nudity (bikini, underwear, cleavage, bare chest), to full nudity (naked bodies) to explicit nudity (suggestive poses, sexual content), it attributes percentages of confidence to your images and videos.

Performance Variations of Image Moderation APIs

For all the companies who use Image Moderation in their software: cost and performance are real concerns. The market is dense and all those providers have their own benefits and weaknesses. 

Performances of Image Moderation APIs vary according to the specificity of data used by each AI engine for their model training. This means that some Image Moderation APIs perform well at detecting pornography while others may perform better at detecting violence in images. If you have customers coming from different fields, you must consider this detail and optimize your choice of provider.

We want our users to have access to multiple Image Moderation engines and manage them in one place so they can reach high performance, optimize cost and cover all their needs. There are many reasons for using multiple APIs:

Fallback provider is the ABCs

You need to set up an Image Moderation API that is requested if and only if the main Image Moderation API does not perform well (or is down). You can use confidence score returned or other methods to check provider accuracy.

Performance optimization

After the testing phase, you will be able to build a mapping of Image Moderation vendors’ performance that depends on the criteria that you chose (languages, fields, etc.). Each data that you need to process will then be sent to the best Image Moderation API.

Cost - Performance ratio optimization

You can choose the cheapest Image Moderation provider that performs well for your data.

Combine multiple AI APIs

This approach is required if you look for extremely high accuracy. The combination leads to higher costs but allows your AI service to be safe and accurate because Image Moderation APIs will validate and invalidate each other for each piece of data.
