 ## Asynchronous Flow (For bulk analysis)
 
 When requesting large amounts of profiles, or when wanting to have more fine-grained control over performance, we recommend using our asynchronous flow. It allows us to process your requests in parallel and get the information back to you more quickly. There are a couple options for using this capability.
