Feedback for eCommerce API landing page is needed

The API doesn't actually exist yet, before developing we want to check if there are actually people will to pay for the data. In the first version of the landing, we offered a test data sample aiming to get any feedback on data quality.
There were more than 100 applies for the sample, but no so much feedback. The central element of the new landing is a price calculator. Its goal is to track what prices and data amount people will set and if somebody will actually purchase some data. What we see now is people are playing with the calculator, but not purchasing.
