Thoughts on my API?

[cloud9]

Hello all, not sure this is the right group for what I'm looking for, if not please send me in the right direction :)

We are thinking of making our API commercially available to the wider developer community and were interested in your feedback; it does a load of great marketing stuff e.g. send or receive voice calls, callbacks, sms, email, Instant or facebook messages. Nearest look up function (from address and location data) and mapping. Data Validation and capture function for residential, email and mobile address. What do you think would people use it??

Thank you! :)
