Directions API

Метод Directions API позволяет вам построить маршрут до конкретной точки.

С помощью этого API вы можете:

Построить маршрут пешком или на машине с учётом пробок на текущий момент или в будущем (на основе статистики).
Указать от 2 до 10 точек маршрута.
Получить информацию о манёврах на маршруте.

Как это работает

Кликните на карту для выбора точек старта и финиша для построения маршрута
