Yes.

In summary:
SOAP is slow and introspective, so servers provide it when they change 
they their API or database structure often, or have a lot of API 
functions. Or have bad managers.
XML-API is the non introspective variant, still overly verbose 
(uncompressed XML tags), but used more often. Non-introspective
means you have to read the documentation for the API. With SOAP you 
could theoretically without.
REST is the hard-core, efficient HTTP based interface, 
GET/HEAD/POST/DELETE only, with readable paths.

With non-HTTP based connections over sockets much more efficient and 
better protocols do exist.
Best known are zeromq for multiple servers/clients, msgpack for run-time 
structures, protobuf for compile-time structures, and many more.
In perl JSON::XS is one of the simpliest and fastest.
