Accurate Forward & Reverse Batch Geocoding REST API Geocoding is the ability to provide geographical coordinates based on a known address. This is also known as forward-geocoding.

Reverse-geocoding is the ability to input geographial coordinates and get an address back from those coordinates.

Doing this is incredibly difficult as there involves a lot of satellite data, human intervention etc in order to get accurate data to build the next Uber or Airbnb.

Thankfully, that’s just what positionstack has done. Positionstack is a geocoding company brought to you by apilayer. They have indexed over 2 billion locations and currently process over 1 billion requests per day.
