K is a language used in finance and database development. To install XML-RPC for K, download it from the Kx website. Uncompress and copy the files into the directory in which you keep your .k programs.
Here's a short client:
| \l kxr
server:("localhost";"/cgi-bin/sumAndDifference.cgi");
.kxr.c[server;"sumAndDifference";2 3] | 
And here's a server:
| \l kxrsc
.kxr.sm: ,("sumAndDifference";{.((`sum;+/x);(`difference;-/x))}) | 
More examples are included in the distribution.
