If you work with data, chances are you've heard of an address lookup API. An address lookup API is a tool that can convert addresses into geographic coordinates (latitude and longitude), which can then be used to place markers on a map, calculate routes, or even search for nearby places.
An address lookup API is a type of web service that allows you to access data about a given address. This data can include information like the latitude and longitude of the address, as well as other details like the owner's name or the property's tax value. Address lookup APIs can be used to build all sorts of applications, from simple mapping tools to more complex geo-targeting applications.
