Which RESTCONF parameter specifies the number of nest levels returned for a GET method?

The parameter that specifies the number of nest levels returned for a GET method in RESTCONF is "depth." This parameter allows clients to control how much of the hierarchical data is returned in the response. By adjusting the depth value, a user can specify how many levels of nested resources they want to retrieve. This is especially useful in complex data models where a resource can have multiple levels of associated data, allowing for efficient data retrieval and reducing the amount of unnecessary data transfer.

Using the depth parameter, clients can optimize their requests according to their specific needs, whether they desire an overview with shallow depth or detailed information with greater levels of nesting included in the response. The capability to define the depth level gives users flexibility in managing how they interact with RESTful APIs, ensuring they get the most pertinent data without overwhelming the API with too much detail all at once.
