# Cat API

The CAT API is a human-readable interface that returns plain text instead of traditional JSON.

## Cat Indices
The following sample code cat indices with required headers and sorted by creation date

```java
IndicesRequest indicesRequest = new IndicesRequest.Builder()
        .headers("index,health,status,pri,rep,doc.count,creation.date,creation.date.string").sort("creation.date").build();
IndicesResponse indicesResponse = javaClient().cat().indices(indicesRequest);
```
