The Geocoding API is a service that provides geocoding and reverse geocoding of addresses.

Geocoding is the process of converting addresses (like a street address) into geographic coordinates (like latitude and longitude), which you can use to place markers on a map, or position the map.

Reverse geocoding is the process of converting geographic coordinates into a human-readable address.

You can also use the Geocoding API to find the address for a given place ID.
