This is very interesting functionality to me, that I would use if it works well. Thanks for trying to clarify what's going on with it.
But when between one fairly poorly documented API that you've told me will soon be deprecated, and another fairly poorly documented API that doesn't have pricing beyond 1K calls a month....
...my response is still "Okay, that could be good in the future, I guess I'll sit back some more and wait for pricing and better docs to show up before paying more attention to it, I hope it does soon!"
I need to know pricing before deciding to use something. And I need good (and google-able! Sorry, even if I'm using Bing API, I'm using Google to look for info on it) docs, along with of course a well-designed API that works well, but I need the first two things before I even get to evaluating the next.
