WorldIP - IP Geolocation, Internet Research

There was the possibility to insert JavaScript (which contained an object with different parameters based on user's IP address) into projects. Now you can get these data in JSON- and JSONP format.

Data returned from API, based on the client's IP address:

JSON

The query format:

http://api.wipmania.com/json

The answer looks like:

{"latitude":"51.0993","longitude":"10.4537","zoom":5,"address":{"city":"-","country":"Germany","country_code":"DE","region":"-"}}

JSONP

The query format:

http://api.wipmania.com/jsonp?callback=YourFunctionHere

YourFunctionHere - your name for the function

The answer looks like:

YourFunctionHere({"latitude":"51.0993","longitude":"10.4537","zoom":5,"address":{"city":"-","country":"Germany","country_code":"DE","region":"-"}})

Example of use with JQuery:

$.getJSON("http://api.wipmania.com/jsonp?callback=?",
 function(data) {
   alert(data.address.country);
});

As for the JavaScript version, there are no restrictions on the number of queries.
