This API endpoint serves the Block Explorer pages by executing a query coined 'Unique Addresses'. Its main purpose is to fetch a list of unique 'from' addresses that interacted with a predetermined blockchain network in a given time range. The parameters required for this API endpoint are 'dates' and 'network'. 'Dates' is a date-range type parameter indicating the start and end date of the period to be queried in 'yyyy-mm-dd' format. 'Network' is a query type parameter and refers to the specific blockchain network to be investigated. The output of this endpoint is a table sorted in ascending order by date, where each row provides the unique 'from' addresses that transacted on the specified network for each given day. Additionally, a 'Unique Addresses Chart' visualization is created to provide a graphical representation of the number of these unique addresses over time.
