# List the dimensions

GET https://api.fastpix.com/v1/data/dimensions

Retrieves a list of dimensions that can be used as query parameters across various data endpoints. Each dimension has a unique id that can be used to filter data effectively.

The dimensions retrieved from this endpoint can be used in conjunction with the list video views and list by top content endpoints to filter results based on specific criteria. For example, you can filter views by `browser_name`, `os_name`, `device_type`, and more.
