Pricing for Test Account

I am curious how the trial works-it says I get 1000 hits for $1, but what happens after that? If I make request number 1001 will my account be billed or will the request just fail since I haven’t subscribed to that package?

The request won’t fail. We track your usage throughout the month and bill you and your “extra requests” rate for any overages, rounding up to the nearest package amount. So in this case 1001 would be billed as $1 for the first 1000 at the beginning of the month, then another $1 for the next 1000 at the end of the month.
