Billing

You are billed on two things

• The bytes stored
• The count of API operations invoked

Storage

The minimum billable object size is 4 KiB. Here is an example — if you have two 11-byte objects in a bucket, they will be counted as 4 KiB each, i.e. 8 KiB in total. 

Storage consumed by each bucket is billed in multiples of 4 KiB, rounded up; Metadata counts towards storage consumed.

Every month, your first 10 GiB is free of charge. Any bytes beyond that are billed at $0.006 per GiB per month. Bytes stored across all buckets are recorded hourly. Usage is subsequently calculated and debited from your balance. 

Here is a hypothetical example:

• You have a $10 balance in your account.
• At time t , you uploaded 11 GiB of objects into various buckets in your account.
• At the next whole clock hour after time t
  • a snapshot of your total storage is recorded as 11 GiB
  • your usage is calculated as (11 GiB - 10 GiB) x ($ 0.006 / 30 days / 24 hrs)
  • that usage is then debited from your $10 balance

API Operations

API operations are classified and billed the following way —
