# About the Credit Data API

The Credit Data API allows you to retrieve information about a site's word credits to help you monitor credit usage and availability. Multilingual sites receive a free word credit quota (1 credit per word) that gets consumed when the [Machine Translation API](https://dev.wix.com/docs/rest/business-management/multilingual/machine-translation/machine-translation/introduction.md) is used.

With the Credit Data API, you can:

- Retrieve a site's word credit data.
- Check whether a site has enough credits to translate a specific number of words. 

## Before you begin

It's important to note the following points before starting to code:

- A Wix user must install the **Wix Multilingual** app on their site.
- Wix users can receive additional word credits by [purchasing a translation package](https://support.wix.com/en/article/wix-multilingual-auto-translating-your-site#purchasing-translation-packages) in the [**Translation Manager**](https://support.wix.com/en/article/wix-multilingual-using-the-translation-manager) at any time.
- Credits are deducted from a site's word credit balance in real-time when machine translation requests succeed.

## Use cases

- [Check for sufficient credits before machine translation](https://dev.wix.com/docs/rest/business-management/multilingual/machine-translation/credit-data/sample-flows.md#check-for-sufficient-credits-before-machine-translation).
- [Create a translation credit dashboard](https://dev.wix.com/docs/rest/business-management/multilingual/machine-translation/credit-data/sample-flows.md#create-a-translation-credit-dashboard).

## Terminology

- **Word credit**: A unit of translation capacity. 1 credit equals 1 word. Every site has a word credit balance indicating the number of words available for translation.
- **Quota**: The total number of word credits allocated to a site, including initial allocation and any additional credits purchased through the [Translation Manager](https://support.wix.com/en/article/wix-multilingual-using-the-translation-manager). Currently, sites have a quota limit, with the exception of [Wix Studio enterprise sites](https://support.wix.com/en/article/wix-enterprise-an-overview), which have an unlimited quota.
- **Machine translation**: The process of using an external service to automatically translate text to other languages. Alternatively, a Wix user can manually translate their content with the Translation Manager.
