This API allows users to fetch the email addresses of all known identities who became known between a specified date range. The API endpoint accepts the start date and end date parameters and returns a list of email addresses for the known identities within that date range.
The start_date is a required parameter while end_date is an optional parameter.
In the absence of the end_date, the API will return a list of email addresses for the known identities from the start_date provided by the user, till the current date.

The accepted format for start_date or end_date is YYYY-MM-DD.
