USgeocoder API is for automatically obtaining data through communications between your server and USgeocoder servers. It's used for internet, intranet or other web-based applications. USgeocoder API free trial is good for 2 weeks or 1000 free lookups, whichever comes first. No credit card information is required at the creation of the free trial account.
If you are looking for an online lookup tool that you can manually enter an address to lookup its location, districts, US Census geographics, and sales tax rates information, please subscribe to USgeocoder Online Lookup Tool which works the same way as the Live Demo.
