Postpaid method is adopted for charge on volume. Cost will be calculated and charged based on the actual use volume of the selected service (such as traffic, number, daily peak, bandwidth, etc.). When charge, if your account balance is insufficient to pay for the bill, arrears will be generated, and the system will send you notice about the arrears. Please recharge the cash when there are arrears, the recharge amount will first be deducted for the arrears. Products with charge on volume supported are as follows:

• Content Delivery Network (CDN) Charge based on traffic and daily peak bandwidth.
• Baidu Kafka: Charge in real time based on your actual use volume.
• Live Streaming Service (LSS): Charge based on traffic, daily peak bandwidth and monthly peak bandwidth.
• Video On Demand (VOD): Charge based on traffic, daily peak bandwidth and monthly peak bandwidth.
• Simple Cache Service (SES): Charge based on e-mail number and traffic.
• Simple Message Service (SMS): Charge based on message number.
• Baidu Search Promotion Live API: Charge based on keyword number.
• Referer keyword data service: Charge based on keyword number.

Take the Content Delivery Network (CDN) as an example:

If you activate the service charged on traffic for the Content Delivery Network (CDN) at 10:00 on January 10 and release the service at 11:30 on January 10, the system will deduct the cost for 60 minutes at 11:00 and deduct the cost for 30 minutes at 12:00.
