# Retrieving MetricBase data using REST and JavaScript

Use JavaScript or REST APIs to insert and retrieve time-series data from the MetricBase database and to run transforms on the data. The transformations enable you to visualize time-series data in a variety of ways.

For more information about MetricBase time-series data transformations, see [MetricBase transforms](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/now-intelligence/metricbase-transforms.md).

## Using REST

For information about the MetricBase REST APIs that return time-series data from the MetricBase database, see MetricBase Time Series API.

## Using JavaScript

For information about the MetricBase JavaScript APIs that return time-series data from the MetricBase database, see:

-   Client — Execute transforms on the MetricBase database and receive the results.
-   Data — Return the object that contains the result of a transform.
-   DataBuilder — Create a series of data points for a metric.
-   Transformer — Manipulate time-series data to prepare the data for evaluation and analysis.
-   TransformPart — Specify details of the transform to be done.
-   TransformResult — Return the object that contains the result of the transformation.

Experiment and get familiar with the JavaScript APIs by using the [MetricBase Data Explorer](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/servicenow-platform/metricbase/metricbase-data-explorer.md) that comes with the MetricBase Demo.
