• Monthly Billing Plans: renew every month and can be cancelled anytime (for example, you can use it for only 1 month and then cancel). After cancelling the renewal, you will not be charged again and can use any remaining requests until the end of your billing period.
• Yearly Billing Plans:  have a 12-month commitment, a single billing at the beginning of the plan, and come with a 30% discount applied (this is why their price is different from the monthly plans).
