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"],null,[]]
