# Filter and select fields

This chapter will teach you how to select and filter out data from our API, which is useful when you want to request specific data and can omit the rest for faster response time. You can filter out data for various parameters per endpoint. See our **endpoint overviews** for more detailed information.

The next three sections are the same as our [request options section](https://docs.sportmonks.com/v3/api/request-options). You can skip this if you've already read it.
