IP-API.com is a website that allows users to lookup the location of an IP address. The site provides free usage of its geolocation API and supports IPv4/IPv6 queries. The API allows users to supply an IP address or domain to lookup, or none to use their current IP address. Data returned includes country, region/state, city, zip code, latitude, longitude and more. The API uses RESTful calls and responses can be formatted in XML, JSON, CSV, Newline Separated and PHP.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
