Example: Currency Rate Function
In[1]:=
Installing an external web service gives Mathematica a
function getRate that looks up current exchange rates:
In[1]:=
Out[2]:= 23.2462
A few minutes later, the rate has changed slightly:
Out[3]:= 22.9165
Example: Searching Amazon
Using Amazon.com's web services
interface, searches can be made from within Mathematica.
For example, evaluating AuthorSearch["Stephen Wolfram", 1],
Mathematica reports the results in an appropriately grouped
notebook.
Example: TerraServer Explorer
TerraServer offers satellite maps of the U.S.
through a web service that is called up in the following example, in
which Mathematica uses an interface constructed with GUIKit.
