使用者輸入查詢時,系統每隔幾次按鍵 (而非每個字元) 就會呼叫自動完成要求,並傳回可能結果的清單。使用者從結果清單中選取項目時,該選取項目會計為一項要求,而搜尋期間提出的所有要求都會合併並計為一項要求。如果使用者選取地點,搜尋查詢本身免付費,系統只會針對 Place Data 要求收費。如果使用者在工作階段開始後幾分鐘內未選取任何項目,系統只會收取搜尋查詢費用。

A session token groups a user's autocomplete search into a single session for billing. Users must create unique session tokens (version 4 UUIDs recommended) for each session, ensuring uniqueness within a project. Requests are bundled into a session. If a user selects a place, only the place details are charged; otherwise, only the search query is charged. Each session ends after a user's selection or inactivity, at which point the token is discarded.\n"]]
