# SingleStore Kai

Use the SingleStore Kai ("the API") to connect to a SingleStore Helios workspace from MongoDB® clients and tools. You can run the MongoDB® queries natively in your SingleStore Helios workspace using the API without a code change. Additionally, you can use the [Management API](https://docs.singlestore.com/cloud/reference/management-api.md) and [Data API](https://docs.singlestore.com/cloud/reference/data-api.md) (SQL endpoint) in conjunction with the API. SingleStore Kai natively supports the BSON data type for storage. Refer to [Kai Data Storage Model](https://docs.singlestore.com/cloud/reference/singlestore-kai/kai-data-storage-model.md) for more information. 

Refer to [Maintenance Release Changelog](https://docs.singlestore.com/cloud/reference/singlestore-kai/maintenance-release-changelog.md) for information on features and improvements introduced since the preview release of SingleStore Kai.

> **📝 Note**: You can only run the MongoDB® commands in your SingleStore Helios database using the SingleStore Kai-enabled endpoint.

**Disclaimer**:

SingleStore is not a MongoDB® partner. SingleStore Kai™ is an API that offers compatibility and enhanced performance for applications built on MongoDB®.

## Why Use the API for MongoDB®

SingleStore Kai offers an innovative, fast, and easy API to perform exceptionally fast analytics on JSON data for your MongoDB® applications without losing transactional performance.

Key benefits to using SingleStore Kai:

* **Drive faster analytics** on JSON data for your MongoDB® applications.
* **Zero code changes and zero data transformations** required for supported commands and operations.
* **Best of both worlds (NoSQL + SQL)**, lets developers utilize both the MongoDB® API and a SQL API to power their applications.
* **Scale-out** SingleStore without any additional cost and simply by defining a shard key.
* **Vector support** lets users provide semantics on vectors using `dot_product`, `euclidean_distance`, and many other functions available through the API.

## How the API Works

The API uses a proxy service (provided by SingleStore) to run the MongoDB® commands and aggregation pipelines. The proxy service receives the MongoDB® commands, generates the SQL equivalent of the command, and runs the SQL in the SingleStore environment. It then reads the resulting rowsets and returns the results as a collection of BSON (Binary JSON) documents back to the MongoDB® client application.
