Lots of new stuff happening here at Data24-7.
Soon, we will be releasing our new API version 2.0. The new API will be faster and more flexible than the existing one; but we'll keep the old API around for existing customers.
Along with the new API will come the ability to add many more cool products to our suite, including zipcode, gender, and mailing address queries, plus new email-related queries.
If you are looking for data which we don't currently supply, send us an email; maybe we can get it.
