I wish it were true pay-as-you-go rather than starting you in a sandbox and then jumping immediately to $150. Working on a small side project, $150/mo is a lot of money in the beginning, especially if I'm doing a relatively small number of requests. I guess I need to see what the sandbox entails, but if it's not real live twitter data, this still feels like a big step function in cost from free to premium. Just charge me per-API call or on the amount of data transferred with no minimum.
