Are all API generally have 'callback' parameter to request it as JSONP ??

I have tried several API such as forecast.io, Disqus, and Dribbble by adding 'callback=[function_name]' and it work, the data I got was passed to the function first argument or if we type 'callback=?' the data will be passed to the anonymous callback function first argument.

So my question is, are all API has the 'callback' parameter or it just commonly used or it is built-in javascript method/logic ?? Dave McFarland

Thanks :)
