How to Choose the Best Address Autocomplete API

The address autocomplete API is an application programming interface (API) that provides type-ahead search functionality. It works by sending queries to your program each time a user types in an address. Addresses are validated and real-time predictions are provided. Address autocomplete APIs can improve the quality of address data. There are several factors to consider when choosing an address autocomplete API. Here are three key considerations to make:

US Autocomplete API returns suggestions based on an index of combinations. It also populates a drop-down menu beneath the user's cursor. You can use the US Autocomplete API to test the user experience on your application by generating a sample cURL request. Smarty's Autocomplete Pro API uses keystroke detection to calculate the correct address. Unlike other address autocomplete APIs, it uses keystroke count to determine the most appropriate suggestions. It also uses standardized addresses and handles accented characters.

Global Address Complete API is another good option. It can detect the country based on IP address, while providing address components in the same language. With global address autocomplete, you can accurately predict the address of a customer worldwide. It works best with API providers that are developed with mapping in mind. However, crowdsourced API providers often lack precision and accuracy. These factors should be considered when choosing an address autocomplete API. If these factors are not met, you may want to choose another provider.
