maps_direction_walking_by_coordinates
Plan walking routes up to 100km using coordinate-based navigation. Get distance, duration, and detailed directions for pedestrian commuting between start and end points.
Instructions
步行路径规划 API 可以根据输入起点终点经纬度坐标规划100km 以内的步行通勤方案，并且返回通勤方案的数据
Args:
origin (str): 起点经纬度坐标，格式为"经度,纬度" (例如："116.434307,39.90909")
destination (str): 终点经纬度坐标，格式为"经度,纬度" (例如："116.434307,39.90909")
Returns:
Dict[str, Any]: 包含距离、时长和详细导航信息的路线数据
