Value to extract, one of: |
A matrix, where rows represent origins and columns represent destinations. Matrix values are according to selected value, or NA if the API returned zero results
The "duration_in_traffic_s" and "duration_in_traffic_text" options are only applicable when the API response contains these fields, i.e., when using mp_matrix with mode="driving", with departure_time specified, and API key key provided
