Hmm, but Google WS does require registration and does not allow you to
put up a commercial search service using it. If you want to use it
commercially, you have to work out a deal with them -- and pay them more
than the ads rate, I suppose. :)

I found Amazon's most useful web API is its XML API not the SOAP
interface. :)

MapPoint.NET has a very complex SOAP interface. It does not work with Axis
out-of-the-box because it requires HTTP DIGEST AUTH. You have to hack the
HTTP transport class a little bit to make it work. Again, MP.NET provides
a 45-day trial. After that, you need to pay big $$$. It is oriented toward
corporate customers who do a lot of Geo-encoding.
