Which fields should I use?

[Ian]

I'm building a tool that, among other things, reports these values for
a given URL: ( http://www.example.com/example/ )


Total Incoming Links ( to any page on target site ) ( *.example.com/
* )
Total Incoming Links to Site Root Domain ( example.com )
Total Incoming Links to Exact Specified URL ( www.example.com/example/
)
Links From Unique Domains ( count of unique domains linking to any
page on example.com )

Can you suggest which data sources from url-metrics I could best use
to get this data?



Also, I'm calculating the number of links from different types of
sites, for example links from .EDU sites. I currently must do this by
downloading the URLs of all linking sites, and then checking each one
for the presence of ".edu" etc. Any chance you can offer an API call
that will do this for me?
