 RTK Query includes these APIs:
 
-- [`createApi()`](./api/createApi.mdx): The core of RTK Query's functionality. It allows you to define a set of endpoints describe how to retrieve data from a series of endpoints, including configuration of how to fetch and transform that data. In most cases, you should use this once per app, with "one API slice per base URL" as a rule of thumb.

 - [`fetchBaseQuery()`](./api/fetchBaseQuery.mdx): A small wrapper around [`fetch`](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) that aims to simplify requests. Intended as the recommended `baseQuery` to be used in `createApi` for the majority of users.
 - [`<ApiProvider />`](./api/ApiProvider.mdx): Can be used as a `Provider` if you **do not already have a Redux store**.
 - [`setupListeners()`](./api/setupListeners.mdx): A utility used to enable `refetchOnMount` and `refetchOnReconnect` behaviors.
