We know there may be some privacy concerns regarding the use of our data but we don't allow anyone to systematically query our API to build phone number lists (We just allow 180 requests per min) We are very strict in the way people use our API. That's the reason we don't have an open registration process.

Yikes 180/m may seem like a lot ... but in the world of data that is a very small amount of usage. Your site says "big data" so this limitation begs the question -- Are you big data (enterprise) or not?

180/m? That's a database of over 10,000 records in an hour, and that's only if the querying party is stupid enough to not think of using multiple API keys in parallel.
