Code example

``"""``

``This is an example script for accessing client-side ASPIS datasets.``

``The client is provided by the ASPISpy package and in particular the connection is resolved by the CaesarAPI class.``

``This example code allows the user to fetch a product from the ASPIS DB and``

``save it in a ready-to-use pandas.DataFrame structure.``

``To use this code to fetch another product, simply change``

``the product name and possibly the time range and columns of the dataset``

``(for the filtered_search method).``

``Notes:``

``- The CaesarAPI class provides a complete interface to the ASPIS DB through several methods,``

``each of which corresponds to a different API endpoint.``

``- Once CaesarAPI has been instantiated through authentication, the user can call the different methods``

``(e.g., CaesarAPI.download_data, CaesarAPI.filtered_search, etc. etc.).``

``- The import and initialization are the same for each code fragment.``

``"""``

``#### The following lines of code should be executed only once``

``#### during session initialization. If they are re-executed,``

``#### the session in ASPIS DB is recreated from scratch.``

``#### Once the session is initialized, the user can use of all``

``#### the methods provided by the CaesarAPI class.``
