# CloudIO REST API playground

CloudIO Platform offers two REST API playgrounds for the developers to make REST API calls.

The first API playground can be accessed via a URI/api for making guided REST API calls. It offers a simple UI for the developer to select a data source and enter the parameter values for performing the REST API calls. The system automatically generates the REST payload in real-time.

The second API playground can be accessed via a URI /jsontest for testing the APIs with a given REST payload. In addition to this, it offers a simple solution for load testing of the REST APIs.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cloudio.io/creating-datasources/working-with-datasources/accessing-data-sources-using-rest-api/cloudio-rest-api-playground.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
