Generate unique session tokens (e.g., version 4 UUIDs) per project. As users type, autocomplete requests are made. Upon selection, all requests are bundled into a single, session-token-linked request. If a place is selected, only the Place data request is charged. Otherwise, only the search query is charged. If no selection is made, the session times out, and only the search query is billed. Discard the token after the session.\n"]]
