# Create an Ask API

> Create an Ask API to query domain data and generate a Data API with an API key.

Creating an Ask API grants you the ability to fetch data and use it in your desired app. After you create the Ask API,
the system generates a Data API and a data API key.

## Prerequisites

* Appropriate permission: `nx1_ask`
* An existing domain created using [DataHub](/platform-components/datahub)
* A previously ingested dataset within a DataHub domain

       * Select a suggested query from the list.
       * Enter a question in the "Add an analysis" field.
