This topic shows you how to calculate the daily fee generated when you call the Content Moderation API.

## Daily fee calculation method

After you submit a moderation request by referring to the API reference, Content Moderation returns machine-assisted moderation results to you. The machine-assisted moderation results may be definite. For example, a result of block is returned if the content contains violations, or a result of pass is returned if the content is normal. The machine-assisted moderation results may be indefinite. For example, a result of review is returned if the content requires manual review.

When you use the Content Moderation API, you are charged based on the amount of data moderated and the machine-assisted moderation results. The amount of data moderated is calculated based on the number of moderation requests for a single moderation object in a single moderation scenario. The unit price of moderation consists of the unit price of data moderated with definite machine-assisted moderation results returned (a) and the unit price of data moderated with indefinite machine-assisted moderation results returned (b). The specific unit price varies with the moderation object, moderation scenario, and amount of data moderated per day. For more information about the unit price of moderation, see Unit prices in this topic. To be precise, you can calculate the daily fee by using the following formula: Daily fee = a × Amount of data moderated with definite machine-assisted moderation results returned + b × Amount of data moderated with indefinite machine-assisted moderation results returned.

## Amount of data moderated per day

The number of requests is calculated based on the number of images or text entries to be moderated. The service is billed once per day. Content Moderation provides tiered pricing based on the number of images and text entries moderated per day by the Content Moderation API. You can enjoy a lower unit price for a larger amount of data moderated per day.

Note The daily fee for videos is calculated based on the number of captured frames.

The following table describes the tiered pricing for the amount of data moderated per day.

Amount of data moderated (Unit: pieces per day) Level
0~5,000 A
5,001~50,000 B

## Unit prices

The unit price of moderation varies with the moderation scenario. The unit price of moderation consists of the unit price of data moderated with definite machine-assisted moderation results returned (a) and the unit price of data moderated with indefinite machine-assisted moderation results returned (b).
• (a) indicates the unit price of call requests for which the machine-assisted moderation results returned are definite.
• (b) indicates the unit price of call requests for which the machine-assisted moderation results returned are indefinite.
