Each new account gets a feature-complete free trial period. This is based on usage, not time, so you can try everything without silly deadlines. The Trial Plan includes $25 of free credits. We won't bill you until that credit is gone.
How we bill
If you have an account with paid usage, and no remaining usage credits, we will bill you a minimum of $10 and apply any overage as an account credit. For instance, if you use $3.50 of service in a month and have no accounts credits, we will bill you $10. Your account will then have $6.50 in credits remaining. If you use $3.50 the next month, we will just deduct usage fees from your existing credits.
