Abstract:

With the number of publicly offered Web service APIs, it's now much easier to get content from different Web sources and to build mashups—if you have access to the right APIs and tools. Discover how you can combine an obscure cross-domain call technique (JSONP) and a flexible JavaScript library (jQuery) to build powerful mashups surprisingly quickly.
