A component of the Yandex.Maps API used for determining the coordinates of a map object based on its address, or the address from the coordinates. For example, for the request [Moscow, Malaya Gruzinskaya ulitsa, 27/13], the geocoder returns the geographical coordinates of this building: 37.571309 ° East longitude, 55.767190 ° North latitude. But if a request sends the geographical coordinates of the desired point [27.525773, 53.89079], the geocoder returns the address: Minsk, prospekt Dzerzhinskogo, 5. In the free version of the Maps API, you can make up to 25,000 geocoder requests per day. To reduce the number of requests, you can cache identical geocoder responses. This will also reduce the load on your website or service.
