Deduction rules
For example, if you do not purchase a resource plan or your resource plan has been depleted, you will be billed for any subsequent API calls. If you incur a bill for 500,000 calls, you must pay the bill using your account balance or another payment method before you can continue to use the API. You cannot purchase a new resource plan to cover an existing bill.
If you have a valid resource plan with a remaining balance, calls will be deducted from the plan first. A resource plan is valid for one year from the date of purchase. If your resource plan is depleted, you are billed at the standard pay-as-you-go rate for your usage.
Important
Resource plans purchased earlier are consumed first.
The traffic billing pattern consumes traffic from the resource plan first.
If your account has an overdue payment, the service will be paused. Service resumes after the payment is cleared.
